2. Combat Aircraft
2.1. Land-based single-engine Fighters
2.1.1. Aigeanta 1T Croman (Harrier) – 1934
Thiaria’s first mass produced fighter aircraft was a very small biplane of indifferent performance, but supreme agility, which was originally developed around a naval specification for a fighter plane suitable to be carried by a rigid airship as organic escort component. The Navy, which never again commissioned any airships after 1918, nevertheless they ordered the plane in considerable numbers; because of its short range, the Croman was never flown from any carrier. Most of the production of 177 machines was never issued to combat units, but used as aerobatic trainers (the air force did not train such fancy stuff itself, but regularly sent its pilots to the navy’s aerobatics training unit). As an advanced trainer, the Croman remained in service till 1942.
2.1.2. Caproni Atlantach 4C Fabhcun (Falcon) – 1936
The Thiarian version of the Caproni Ca.114 was built only in 90 copies domestically and flown by a single fighter wing between 1936 and 1940 without ever seeing action before being phased out and used for training. The type was however license-built in Peru (64) and Mexico (80), where it flew till 1943/4 in frontline units and was apparently well liked.
2.1.3. Aeraon 4A Seabhac (Hawk) – 1937
The main reason why the Fabhcun only ever saw a very limited production was the simultaneous availability of this aerodynamically very clean biplane which ranked among the best biplane fighters ever built, although it did not last as long in service as the comparable I-153 or CR.42. Although the Seabhac’s Hispano-Suiza 12X engine was slightly weaker than the Fabhcun’s radial, the Seabhac was both faster (420 versus 395 kph) and more maneuverable. 477 were produced, and the type saw exports to Argentina, Spain, Venezuela and – one of the very few sales of Thiarian equipment to middle and eastern Europe – Greece. Its use by the Greek Air Force in 1941 also made the Seabhac one of the few fighters to be employed by both sides during the war. In Thiaria, it equipped three fighter wings for some time before it was phased out from mid-1941. They were retired from operational units by mid-1942; by that time, they had seen only few combat sorties against the still very rare and ineffective British incursions into Thiarian Airspace, but still were considered effective and reliable. Over 300 were handed down to training formations and remained in use throughout the war in ever-dwindling quantities.
2.1.4. Aigeanta 2T Clamhan (Buzzard) – 1938
Thiaria’s first shot at a monoplane fighter was exactly the failure it looked like. Slower than the biplane Seabhac and less maneuverable, the Clamhan failed to win any production contracts. Only 2 prototypes were built.
2.1.5. Aeraon 6A Cobra (Cobra) – 1940
The Thiarians took their time developing a worthy successor for their successful Seabhac biplane. Aeraon’s own entry into the competition was obviously influenced by the Dewoitine D.520 outwardly and initially had the same Hispano-Suiza 12Y engine; the plane was however larger, aerodynamically more refined and used notably larger wings. Internally the Cobra was better optimized for mass production than the D.520 (or any other Thiarian fighter, for that matter) and offered considerable growth potential. It was considered equal to its primary competitor, the Caproni Atlantach Iolar, in terms of performance (except range, where it was clearly better) and could be built at half the time for two thirds the cost. The Cobra was commissioned in 1940 to replace the Seabhac and eventually became Thiaria’s most produced aircraft type ever, with some 5.100 built as Fighter, LIFT and Photo Recce Aircraft for both the Air Force and the Navy. The fighter version, which was exported to Argentina and Uruguay during the war, quickly established itself as a respected opponent for most allied airplanes. With their 1.200 hp Hispano-Suiza 12Y engines for speeds of 585 kph and their armament of one 20mm cannon and six 8mm Machineguns, the T6A-1 were nearly equal to the Spitfire II and superior to early P-40s or any version of the Hurricane. 833 of the initial version were built, and these fighters quickly became standard issue for Thiaria’s entire fighter force; only two of Thiaria’s eight day fighter wings were not equipped with them. In 1942, the basic design was considerably improved to T6A-3 standard by installing a 1.600hp Hispano-Suiza 12Z-17 engine. Airframe and engine turned out to be a match made in heaven, with a top speed of 665 kph easily achieved. 1.093 were built and used heavily during the invasion of Uruguay and the subsequent land offensive into Brazil. As the war progressed, uprated versions of the 12Z – first the 12Z-34 with 1.750 hp, then the 12Z-43 with 1.900 hp – were installed, increasing top speed to 685 and 710 kph, respectively. The 12Z-34 powered machines (T6A-7, introduced in mid-1943, 1.387 built) had stretched hulls, bubble canopies and replaced their six wing mounted 8mm machineguns with four 13mm guns, and the 12Z-43 powered fighters (T6A-12, only 141 completed during the war) added two more 13mm guns, bringing the total back to six, which gave them most impressive firepowerby anyone’s standards. These fighters were still competitive with the latest foreign types when Thiaria dropped out of the war. A navalized version T6A-6 appeared in mid-1942 and drastically improved the performance of Thiaria's carriers (see separate entry below), and 567 (of all motorization variants) were completed as LIFTs. The Cobra remains Thiaria’s most famous fighter of the Second World War, which was in action everywhere Thiarian forces fought and always gave a good account of itself. Although not as maneuverable as the Spitfire, late editions of these fighters could climb and dive with most contemporary versions of the Thunderbolt (except the P-47M) due to their very good power-to-weight ratio; they could exceed 900 kph in a steep dive without major structural problems. They were clearly superior to every contemporary variant of the P38, P39, P40, P63 and F6F, and they performed irritatingly well against Mustangs; they would have found their masters in the P51H and the Griffon-Spitfire, but never met any of them. Counting only air-to-air combat, the Cobra achieved a favourable kill ratio of 3,6:1; if all kills and reasons of loss are factored in, the ratio drops to 1,4:1 due to many of them being destroyed on the ground late in the war. Cobras destroyed 70% of all airplanes killed in midair by Thiarian aircraft, and the top 10 Thiarian Aces all flew the Cobra for most, if not all their career, including Thiaria’s ace of aces, Maj. Padraig Coltraine with 88 confirmed kills. The Cobra was also widely used as a fighter-bomber in 1944, when many pilots refused to fly the structurally unsound Ollpheist planes of the light bomber wings and several hundred surplus T6A-3 (280) and T6A-7 (210) Cobras were made available to them; these machines received wing pylons for up to 750 kilograms of ordnance (typically, two 100mm rocket quadpacks, four 170kg bombs or or two 340kg bombs). In addition to the 3.821 land based fighters, fighter-bombers and fighter-trainers, there were over five hundred photo-recce airplanes – all of them with 12Z engines – which have a separate entry below; the same goes for 800 navalized Cobras.
2.1.6. Caproni Atlantach 9C Iolar (Eagle) – 1940
Thiaria’s only other mass-produced land based fighter design besides the Cobra was based upon the Italian Caproni-Vizzola F-Series, which the Thiarians mated to a Hispano-Suiza 12Y-89 engine of 1.200 hp. The combination worked well, and the resulting fighter offered performance comparable to the Cobra in most respects except range. Maneuverability however was rated slightly superior, and flight characteristics were reported as more docile and pleasant by most pilots. Armament was weaker, with only two 8mm machineguns supplementing the single 20mm cannon, but the main drawback was the complicated construction method based on Italian pre-war practice which cared little for the necessities of mass-production. Although the Thiarian government kept ordering Iolars and approved upgrades – mostly as a precaution should Cobra production run into difficulties – the type never achieved the Cobra’s ubiquity. The initial version T9C-1 – which was named Iolar Firean (Stone Eagle) and was capable of 590 kph – equipped a single fighter wing; 175 were built. When the Hispano-Suiza 12Z-17 was fitted to the Iolar in mid-1942, the accompanying changes in structure (including a switch to an all-metal fuselage) were sufficiently comprehensive to warrant a new name, and the 12Z-equipped machines, which also replaced the 8mm guns with 13mm ones, were named Iolar Rioga (literally Royal Eagle, actually referring to the Harpy Eagle, of which considerable populations are native to Thiaria). Depending on which version of the 12Z was installed, the Iolar Rioga achieved top speeds of 670 kph (T9C-3 with 1.600hp 12Z-17, 294 built), 695 kph (T9C-5 with bubble canopy and 1.750hp 12Z-34, 350 built) and 720 kph (T9C-7 with 1.950hp 12Z-43, only 55 built). 180 of all versionswere completed as LIFTs. There was no photo-recce version. Also unlike the Cobra, the Iolar was never used by any expeditionary forces, but limited to home defence; in the day interceptor role, their somewhat austere armament proved quite a hindrance, although they were at their best when dealing with escort fighters. Remarkably, the Thiarians managed to ship a total of 60 to Peru in the middle of the war, where the type was also license-produced (125 units not counted in the total below, all of them with 12Z-17s) and flown till 1958 in combat and training roles.
2.1.7. Aerelar 4L Saighduir (Archer) – 1944
With the Cobra and the Iolar in full production, both of which displaying considerable growth potential in terms of engine power, development of new land-based fighters with piston engines enjoyed very low priority during the war. The Thiarian Air Force was aware as early as 1942 that the future belonged to jet propulsion. The Navy however still felt a need for piston-engined fighters due to the short range typically associated with early jet aircraft. Aerelar had started to develop a high-powered carrier-based fighter (Aerelar 5L Siolpaire, see below) with the 2.150hp Trenhaile 18T engine in 1942, but ran into trouble when this big powerplant could not be produced in the necessary numbers and was assigned to other projects with higher priority. With their production facilities sitting idle and the prospect of being ordered to license-build other people’s aircraft and close down their design department, Aerelar embarked on a crash programme to build a land-based high-performance piston-propelled fighter which nobody had ordered and for which there was no defined requirement. They had acquired the plans for the Italian Reggiane Re.2005 Sagittario in 1943 and adapted them to the 1.900hp Hispano-Suiza 12Z-43 which entered series production early in 1944; they also strengthened the structure and added a bubble canopy. The result was a fighter that outperformed not only both existing Thiarian standard fighters, but also pretty much everything the Allies had to offer; the Saighduir, as the plane was called by literally translating the Italian ‘Sagittario’, was one of only two axis fighters with piston engines that could fight an early Griffon-Spitfire on even terms, and it became available nearly a year earlier than the other one, the Focke-Wulf Ta152C. It featured a top speed of 725 kph, had three 20mm cannon and maneuvered like a devil. Although there was no chance that this plane could ever replace the Cobra, whose series-production was humming at full steam in 1944, Aerelar was allowed to build as many of them as possible until the Siolpaire became ready for production. This resulted in a very limited production run of 114 machines in 1944; they enjoyed priority in 12Z-43 deliveries over all other Thiarian fighters. These planes were assigned to three squadrons serving with three different wings, all of which were tasked with home defence; although they made quite an impression, by that time it was too late for them to have any impact upon the outcome of the war.
2.1.8. Caproni Atlantach 14C Tintreach (Lightning) - 1944
Thiarian Aircraft industry had begun to concentrate on jet fighters early in 1943; at that point, all work on follow on piston engined day fighters ceased with only few exceptions where range was considered a paramount requirement. Caproni Atlantach devoted considerable effort to the design of the smallest-possible airframe capable of accepting the TDA (Tuirbadinimice Aonta / United Turbodynamics) RT1A axial turbojet of 7,5 kN thrust then under development. Despite its superficial similarity with the Jumo 008, this engine was an all-Thiarian development, although some of the project-leading engineers had worked in Germany before the war. The plane, which sported a quintessentially Caproni-like appearance, like a scaled down CC.1, had its maiden flight in August 1944, when Thiaria already was at the brink of collapse. Capable of 830 kph and armed with two HS404 20mm cannon, the Tintreach seemed an ideal home-defence interceptor at that time; it was no true multi-role plane like the Me262, but more like a Thiarian version of the He162 with an emphasis on ease of construction and handling. Unlike the He162, the latter objective was actually met; the Tintreach was pleasant and rather forgiving to fly, if mechanically not very reliable due to ongoing teething troubles with the engine. There was no series production, but several subcontractors assembled about two dozen planes late in 1944, when Thiaria was already descending into chaos. Only half a dozen were actually commissioned, but there were no operational sorties anymore.
2.2. Land-based multiengine Fighters
2.2.1.Aigeanta 3T Coirneach (Osprey) – 1939
Thiaria’s first attempt at creating a twin-engined multirole fighter had its maiden flight early in 1939. This type of aircraft is a natural choice for Thiaria’s Air Defence Force, which has to defend a huge land and sea area with comparatively few assets, so range is a crucial factor for them. Range is equally important for offensive missions, like escorting the new Nairn 2N Scriostoir bombers then under development. With two Hispano-Suiza 12Y engines of 860hp (later versions 930hp and 1.100 hp, respectively), an armament of two 20mm cannon and four 8mm machineguns and a large fuel supply for the specified range of 2.500 kilometers, which was quite much by 1939 standards. Its drawbacks were pretty much the same as with most planes of this type; they were heavy on the controls and not maneuverable enough to mess with single-engine fighters. In addition, the 12Y was not very well suited to this rather heavy airframe, limiting top speed to 485kph (even the up-engined versions, which were also heavier due to added equipment and armour, never exceeded 500kph). Since there were grave teething problems with both proposed successor models, the Coirneach, which at least was stalwartly reliable – remained in small-scale series production till 1942 and was not retired before late 1943, when the CSCA Tornado had finally been developed into a truly formidable fighter. Coirneachs – both specially produced and refitted ones – remained in use as target tugs for the remaining duration of the war. 475 were built in total.
2.2.2. CSCA 5S Tornado (Tornado) – 1940
Judging from its beginnings, it was a major surprise that the Tornado would eventually become Thiaria’s premier twin-engined fighter and acquire a fearsome reputation amongst all who had to fight it. The basic design competed with the Aigeanta Ollpheist to become Thiaria’s future long-range multirole combat aircraft equally suited for day and night fighting, bombing, and photo reconnaissance (the Coirneach lacked this sort of versatility due to its diminutive payload). The Tornado featured a sturdy all-metal hull of rather large dimensions, but very good aerodynamic shape, a stretched glass-house cockpit with excellent visibility for its crew of two (optionally three), large integral wing tanks for a range of 2.500 kilometers, a powerful armament of four 20mm cannon and four 13mm machineguns (plus a fifth firing aft in the rear cockpit) and enough space and weight reserves to add further equipment like cameras or radar gear. Unfortunately, this considerable package was powered by nothing better than a pair of license-produced French-designed Trenhaile (Gnome-Rhone) 14N radial engines of 1.150hp apiece, which was nowhere near enough for a plane of this size and weight, resulting in disappointing performance of the S5S-1 fighter version (speed only 470 kph, slower than the Coirneach the Tornado was to replace, indifferent flight characteristics, grave overheat issues with the engines and the inability to take more than 500 kg payload, as opposed to a specified requirement of 1.500 kg). The G5S-2 recon version, which had no 20mm cannon and was somewhat lightened, was slightly better at 495kph, but generally the Tornado was deemed a major failure, and the first 120 production aircraft were quickly retired from the front after some very disappointing encounters with Brazilian fighters. By late 1941 however, Trenhaile was series-producing the Gnome-Rhone 14R-1/2 of 1.400hp and prepared for series-producing the 14R-4/5 of 1.600hp, and it had already been determined early in 1941 that the Tornado could easily take this much more powerful engine with minimal structural modifications. The S5S-3 with the 14R-1 (81 built) had already much improved performance, not only in terms of speed (550 kph) but also – more pronounced – in terms of maneuverability and flight characteristics. The S5S-4 introduced the 14R-4/5 late in 1942 and finally had become the fighter it was always meant to be. With a top speed of 605kph and really good agility for its size, it was a dangerous opponent for any allied fighter when it arrived at the front early in 1943, used mainly as a long-range escort for heavy bombers or land-based maritime strike aircraft and as a patrol fighter to protect convoys and naval units operating close to the coast. As a strike fighter, it could carry up to four four 340kg bombs externally. At 488 units, it was the most produced fighter version, and many were used in the ground support role. The S5S-7 night fighter version followed in due course and quickly became the mainstay of the Thiarian home defence in the last two years of the war. Of the 1.016 Tornado fighters produced in total, 327 were night fighters. They were easily the most popular and successful Thiarian twin-engine fighter, and remained in production throughout the war.
2.2.3. Aigeanta 4T Ollpheist (Wyvern) – 1941
Like the Tornado, the Ollpheist, Thiaria’s other proposal for a multi-purpose combat aircraft, encountered severe teething problems when it was introduced. Very much unlike the Tornado, the Ollpheist was never really cured of them; although it remained in production for the entire duration of the war and was credited (on paper) with considerably better performance than the Tornado, it can justly be regarded as the biggest lemon in Thiaria’s inventory. The Ollpheist was designed to an entirely different philosophy than its direct competitor, the Tornado: Whereas the Tornado was heavy, but sturdy, everything about the Ollpheist was optimized to save weight for maximum performance. Hull and wings consisted mainly of wood in a Mosquito-like fashion, armour was nonexistent and weight reserves were minimal. This resulted in serious structural deficiencies, which were less troublesome with the bomber version F4T-1 which was after all supposed to avoid situations where maneuvering stresses might occur, but rendered the Fighter version F4T-2 – which carried two 20mm cannon and four 8mm machineguns and was a devilishly fast plane for its day at 580kph despite the rather weak 930hp Hispano-Suiza 12Y engines – practically useless. Several dozens were destroyed when they literally fell apart in midair during combat maneuvers, and only the troubles with the underpowered initial versions of the Tornado kept the Ollpheist’s fighter version in production. 121 12Y-powered fighters were built. Up-engining the Ollpheist with the 1.450hp Hispano-Suiza 12Z-1 boasted performance further (speed for the S4T-3 prototype was 630 kph), but did little to ease the structural problems; the bomber versions received additional structural strengthening, but the fighters, of which 139 were built, were even more overtaxed than before. When the Tornado finally was fully matured, it was decided to cease production of the Ollpheist’s fighter version after merely 260 planes and concentrate on the bomber versions that were marginally more useful. When the Brazilians had received enough Liberators to bomb Montevideo and New Portugal big time late in 1943, a radar-equipped night fighter version of the Ollpheist was developed in a crash-programme. These planes (S4T-7) combined the 12Z-1 (the wing structure could not take any of the more powerful versions of that engine) with an armament of two 20mm cannon and four 13mm machineguns and a radar set; they were good for 615kph, still faster than the Tornado, and performed more or less satisfactorily when not forced into dogfights, but were only produced in 73 copies before all was over.
2.2.4. Aeraon 7A Bultur (Vulture) – 1944
Thiaria’s final attempt at a go-everywhere do-anything combat aircraft was the first one that yielded instant success; unfortunately, this success came no earlier than mid-1944, when it was already too late to produce the necessary numbers to make a difference. Originally designed as a heavily armed attack bomber with two 2.150hp Trenhaile 18T engines (an upscale of the 14R with four more cylinders and slightly increased displacement per cylinder), the Bultur was pressed into night-fighter service as soon as it was ready for series production. It received an obscenely heavy armament of eight 20mm cannon, four in the bow, two in the wing roots and two in the rear fuselage firing upward at a 30° angle. Despite the weight of the guns and all their ammo, and despite the drag of the radar system with quad German-style antennae, the plane was good for 650kph, almost as fast as a He219, and almost as maneuverable too, although its range of 1.700 km was considerably shorter than the Tornado’s. Against the B24s used by the British and Brazilians during 1944, the Bultur’s capabilities were almost wasted (it had been developed to kill B29s, after all), and they inflicted losses out of proportion to their limited number. When the armistice came in October 1944, the survivors of the 102 produced Bultur fighters equipped a full, if somewhat understrength, night fighter wing.
2.3. Carrier-based Fighters
2.3.1. CSCA 1S Condar (Condor) – 1934
As soon as Thiaria was officially allowed to establish military aviation in 1931, one of the first specifications for a domestic military airplane asked for a carrierborne twin-seat long-range fighter, escort and scouting airplane with secondary light attack capability. The Condar, a very conventional and old-fashioned biplane powered by a 680hp Hispano-Suiza 12X, was the winner of a prolonged evaluation between several designs and was introduced into military service late in 1934. Production ran for three years and yielded 110 machines. Although the Condar was invaluable as a training and experimental aircraft that allowed the Thiarians to catch up with the major sea powers in carrier training and doctrine prior to WW2, it never saw operational service and was never flown from any of the other Thiarian carriers. It was retired from the front line in 1939 and from training units in 1943.
2.3.2. CSCA 3S Foiche (Wasp) – 1938
The Foiche was developed to the same specs as the Condar, although at a generally higher performance level. The Thiarian Naval Aviation needed till 1942 to realize that carrierborne fighters did not really need the second crewmember, but rather better agility; by 1938, the Foiche, whose performance is best compared to the Skua’s, was considered the pinnacle of carrierborne fighter design. With its 900hp Gnome-Rhone 14K engine, it was good for 420kph, although not very maneuverable due to its bulky size and prone to engine failure as the 14K was ill-adapted to naval service. The 14K engine was replaced by a more powerful and much more reliable license-produced Trenhaile (Gnome-Rhone) 14N of 1.150hp in 1940, and in this configuration, the Foiche could manage 450kph – more than a contemporary Fulmar – and gave a good account of itself in the first major engagements between Thiarian and British carrier planes during 1940 and 1941 despite the rather weak armament of six 8mm machineguns. Due to problems with the underpowered initial versions of the proposed replacement Cearnabhan, the Foiche remained in production till mid-1942 and in service till mid-1943, considerably longer than planned; the last ones operated from escort carriers in 1943. By that time, they were no longer fit to fight contemporary allied shipborne fighters, and only very few remained when the type was finally retired. 304 were produced, 169 of them with 14N engines.
2.3.3. Caproni Atlantach 10C Cearnabhan (Hornet) - 1941
The Cearnabhan is a Thiarian version of the Italian Caproni Ca.335, also produced in Belgium as the SABCA S.49. Unlike the Italian and Belgian versions, who were reasonably sporty performers despite their rather weak 930hp engines, the Cearnabhan featured enhanced wing and fuselage structure, strengthened undercarriage, arrestor hook, heavier radio gear and additional fuel for almost twice the range, thus becoming much heavier than the original. Despite having a stronger 1.200hp Hispano-Suiza 12Y-89 engine, the Cearnabhan was only good for 425 kph due to excessive weight, considerably slower than a Fairey Fulmar, its most closely comparable contemporary contender. The first 110 machines were judged unsuitable for front-line service after a short time and only used for training; the predecessor model Foiche was kept in service for much longer than planned for that reason. As the Cearnabhan had some considerable advantages over the Foiche, however – longer range, an armament of one 20mm cannon and six 13mm machineguns, better maneuverability due to superior aerodynamics and a much more robust construction capable of taking enormous punishment – the design was kept in production after the new Hispano-Suiza 12Z-1 engine of 1.450hp had been fitted, which finally gave the T10C-2 adequate speed and climb characteristics (top speed 500 kph) and a useful payload of 1.000 kg; 164 were built. In this configuration, the Cearnabhan quickly spread through the Thiarian fleet. The type was continuously fitted with ever stronger engines, first the 1.600hp 12Z-17 in late 1942 (T10C-3, the most numerous version with 178 units, top speed 540kph) and finally the 1.750hp 12Z-34 (T10C-4, top speed 560 kph, 120 delivered) in early 1944. The Cearnabhan remained in service throughout the war, although it was only flown from escort carriers from early 1944, and delivered sterling and useful service as escort and patrol fighter, long-range recce aircraft and auxiliary ASW platform. It was about equal to the Fairey Firefly as a fighter and stood a fighting chance against a Hellcat on a sunny day, but was lost against a Corsair or Seafire.
2.3.4. Aeraon 6A Cobra (Cobra) – 1940
Thiaria's lack of high-performance single-seat carrier planes was not felt very painfully in 1941 due to the similar lack of such planes in the British and Brazilian fleets, but during 1942, their carriers started to encounter Martlets and Seafires, with sobering results. Aeraon had started development of a navalized Cobra powered by a Hispano-Suiza 12Z-1 in 1941; it differed from the land version by having more wingspan, half again the fuel capacity, arrestor gear and a strenghtened undercarriage. Armament was cut to one 20mm cannon and two 13mm HMGs. The resulting T6A-6 entered production in April 1942 and had nearly the range of the much heavier Martlet with much superior performance in every other respect, having a speed of 600 kph and retaining the land-based Cobra's good maneuverability. 216 were built and gave a good account of themselves. The engine was changed to the 12Z-17 with 1.600hp early in 1943; the designation remained T6A-6 as the plane remained unchanged otherwise. With a speed of 635 kph, the T6A-6 was a match for the Hellcat, and 334 were built. The final upgrade yielded the T6A-10 early in 1944, which had a bubble canopy and was powered by a 1.750hp 12Z-34 and capable of 670 kph. 243 of these machines, which were a match for the best Merlin-Seafires or early Corsairs, were built. This version also received two additional 13mm HMGs in the wings. The navalized Cobra had its combat debut in November 1942 and served on all Thiarian fleet carriers for the remainder of the war; its proposed replacement T5L never made it to series production. Of the 793 units built (including 140 carrier-capable LIFTs of all versions), two thirds served aboard Thiarian carriers at some point in their careers, and they always remained in touch with the performance of their allied counterparts. Despite very high attrition, there were always enough machines available to fully equip the Thiarian fleet carriers, and their pilots were the absolute varsity in Thiaria's armed forces; due to the absolute priority of the Navy in Thiarian military hierarchy, it was common practice to give the most promising Air Force pilots carrier training and transfer them to the Navy in case of losses.
2.3.5. Aerelar 5L Siolpaire (Vampire) - 1944
Thiaria’s equivalent to the Corsair and the Mitsubishi A7M was a most impressive airplane with a wing-mounted armament of two 20mm cannon and four 13mm machineguns, a very rugged structure capable of taking enormous punishment and a very long range (radius of action 1.300km). Unfortunately, the whole package was so heavy that the original Trenhaile 18T-1 engine of 2.150hp was incapable of providing the specified speed of 650 kph when the Siolpaire had its first flight in March 1944. Development of a 2.500hp version of the 18T dragged on with no tangible results throughout the war; as the navalized Cobra was performing exceedingly well, series production of the Siolpaire was postponed again and again and finally cancelled in October 1944 after the downfall of Thiaria's fascist regime. Only half a dozen prototypes and trials aircraft had been built.
