Hello again!
@ace: according to the accompanying text, they had nearly 9.000 tons; I figured that should be enough for Terrier. Maybe there was not enough belowdeck space for bigger magazines on the Dutch cruisers; the magazines they use are a deck lower to begin with. But that's just speculation.
@Krakatoa: After two wars on the wrong side, no way the Thiarians would be allowed to keep anything larger than a light cruiser in the 1948 peace. Four 13.500-tonners will come, but these will become allied prizes.
Now to something completely different:
3.4. Coire-Class
With Oirirceas and Ardcheim, Thiaria had used up all the cruiser tonnage allotted to her in the 1930 LNT. If any more cruisers were to be acquired, some trickery was required. One obvious solution was building ships which were in fact cruisers, but disguised as another category of warship. The Thiarian navy had always placed emphasis on offensive mine warfare, so they decided to create a fast minelayer which could double as a destroyer leader if needed. As the LNT designated every vessel with 140mm guns as cruisers, they needed a smaller calibre; fortunately, a very capable 130mm/45 piece was available, for which a fully enclosed twin DP mount was under development since 1932 for the Conlan-class battlecruisers. In 1934, a design was prepared which carried four 130mm twin DP mounts, superimposed fore and aft, and four of the new 37mm quad AA mounts then under development, two on either beam. Eight quad mounts for 13mm machineguns completed the armament. Rails for 300 mines were provided on quarterdeck level; mine rails extended over 60% of the hull length, and the mines were discharged aft. A long, sleek flush-decked hull of 5.800 tons standard displacement was built around a 96.000 hp engine plant, which would provide 35 knots of design speed, essential for an offensive minelayer which would regularly need to leave its area of operations in one big hurry. Unusually for Thiarian ships, the engines powered four shafts. Range was set at 7.000 miles at 15 knots. Aerial scouting capability was provided by a single catapult and one scoutplane. Armour protection was radically changed compared to earlier Thiarian cruisers; these vessels were the first without a vertical belt since 1912. Instead, they were fitted with a 40mm armoured deck above the vitals plus armoured boxes of 90mm vertical strength around the magazines and steering gear. The Machinery, consisting of two standard destroyer-type plants, had only 20mm splinter protection, but good internal subdivision (four autonomous units of one turbine and two boiler rooms per unit arranged en echelon, with the uptakes of two units trunked into a single funnel and all units divided by void spaces; auxiliary machinery had separate compartments). The superstructure, mast and funnel arrangement intentionally bore a certain resemblance to contemporary British and Recherchean light cruisers from a distance, the main difference being the superimposed turrets aft and the longer quarterdeck. Finding the right stern shape for minimum turbulence required some experimentation, and it took the Thiarians till mid-1935 to perfect the design. Construction of two ships was funded under the 1935 estimates, although this decision met severe criticism. For a fast minelayer, these ships seemed awfully large, complex and expensive; for a full-fledged cruiser, they seemed awfully poorly armed and protected (they were larger and visibly longer than Britain's Arethusa-class, but carried smaller main guns, no intermediate artillery, and much less armour). But construction was approved anyway; real cruisers were politically not feasible at that time, and these ships were all that could be done. Both contracts went to the same yard, CTS at Abernenui, which had guaranteed completion within 36 months. Both were laid down in 1936 and named LT Coire (Gaelic: Justice) and LT Comhcheangal (Gaelic: Alliance). Soon after they had been laid down, the second LNT eliminated numerical restrictions to the light cruiser fleets of the signatories, and the whole idea behind the design became invalid. Many in Thiaria believed it would be best to axe them in favour of additional Oirirceas-class units. The Thiarian govenment however decided to keep them with a kind of persistence unusual for such an unpopular project. That bribes by the CTS yard were involved was not revealed prior to 1939, placing procurement of these vessels into a string of rotten deals struck in the late 1930s by Thiaria's last pre-war conservative-liberal government (another notable one was the purchase of 200 AMC-35 tanks from Renault). The Navy decided against additional Oirirceas-class vessels in 1937; if any additional 'real' cruisers were to be built, they would have to be a new generation of heavy cruisers matching the performance of the best foreign designs, and these were yet in the design stage and could not be laid down before mid-1938. So Coire and Comhcheangal were built, although not as quickly as promised because other projects were prioritized, and in the end were above budget by nearly 100%. Coire was completed in June 1940 and Comhcheangal in October; both had the longest building periods of all Thiarian interwar cruisers. At the time of their completion - they were the first Thiarian cruisers to be painted blue all over for minimum visibility from the air - they looked like this:
Trials and workup were conducted with utmost haste; only Coire performed a maximum power run, where she made 37.7 knots at nearly 110.000 hp. Continuous sea speed was 32.5 knots, an excellent figure which made them well suited to co-operate with destroyers. With radar systems still in short supply, these ships did not receive any prior to late 1941. Neither took part in the disastrous battles against the British in early 1940. With Thiaria's cruiser fleet decimated, both were pressed into fleet service, where their good AA fit was of some value; during all of 1940, neither embarked as much as a single mine. Coire took part in three raids against the Cape route in 1940, Comhcheangal only in the last one, which was very successful; Coire sank a British sloop and a merchant with gunfire. Early in 1941, in preparation for the attack against Brazil, they finally embarked some mines and made several nightly trips into Brazilian territorial waters to deny some smaller southern Brazilian ports to the enemy. During the invasion proper, they reverted to fast carrier escorts; they did not make contact with enemy forces, but Coire shot down three land-based Brazilian airplanes just prior to the battle of Cairnmallacht. When New Portugal was secured, both were taken in hand for installation of a full radar suite; they also swapped their 32 13mm machineguns with 16 20mm cannon, and added eight more in single mounts. The refit, scheduled to last six weeks per ship, dragged out for most of the rest of the year due to the anti-communist purges in the third quarter of 1941. Both took till December 1941 to return to the fleet. Comhcheangal looked like this in her blue-black camouflage for night operations:
Comhcheangal was dispatched for another high-risk mining mission towards Capetown under cover of a severe summer storm in January 1942; she managed to escape undetected, but her drifting minefield was too dispersed and failed to catch any prey. Coire went on a similar mission a month later, but this time, the Recherchean cruiser Condringup was waiting for her and hit her fifteen times with 152mm shells while she ran for home at 37 knots after having jettisoned her mine load. Coire could shake off the Rechercheans, but her engines failed 180 miles out of port and rendered her adrift. Condringup, already en route back to Capetown, picked up a coded distress call and reversed course, but a Thiarian submarine patrolling the area attacked her with torpedoes. Condringup evaded them, but her skipper believed he was heading into a submarine trap and retreated. Coire was eventually towed to safety by the destroyer LT Ropanta. Her superstructure and engines were badly damaged, and repairs took nine months. The episode had clearly proven that offensive mining operations by surface ships were very much a thing of the pre-radar age, and would remain the last such sortie for the Thiarian minelayer fleet. Comhcheangal was assigned to the carrier strike force during the first half of 1942, alternately covering the carriers against land-based air attacks during their support of Army operations in Brazil or being kept in reserve in New Portugal. In August, she accompanied a major raid against Capetown; her boats landed a party of commandoes that blew up a British ground radar station and enabled other Thiarian cruisers to steam close enough to the coast to bombard a British airfield. In the battle of Meanhchiorcal, Comhcheangal was not damaged; she shot down six airplanes and evaded an aerial torpedo. As she was judged too short-legged for the Panama Raid, Comhcheangal was assigned convoy escort duty between Thiaria and Montevideo during that time. On November 22nd, 1942, she accompanied three larger Thiarian cruisers during an engagement with inferior Brazilian forces, and damaged a Brazilian destroyer with gunfire. Due to the decision not to risk large surface minelayers on offensive mining missions any more, Coire had her mine rails removed during her repairs. Part of her side plating was removed to install two quad torpedo launchers, and she received Asdic, Hydrophones, two DC racks and two DC throwers on the cut-down stern for use as a destroyer leader; with her four-shaft engine plant, she had the necessary maneuverability for that task. The 37mm directors were also finally fitted with radar. When she returned to service in November 1942, she looked like this:
Comhcheangal received a simliar refit in January and February 1943, but her stern was not cut down because Coire's tended to cut under at certain speeds, rendering the ASW weaponry useless. She also did not receive K-guns, and her depth charges were stowed on the former mine rails. Both re-joined the carrier strike force after the return of the Panama raid task force. During the Battle of Faoigabhar in May 1943, Coire and Comhcheangal each led a destroyer squadron and were involved in some vicious infights with allied light forces. Neither scored a kill (although their destroyer squadrons did), and Coire was damaged by the Free French destroyers Audacieux and Fantasque with nine 138mm hits in the initial phase of the battle. She was rescued by the new heavy cruiser Caitriona, which sank Audacieux with gunfire. Comhcheangal stayed close to the Thiarian carriers and did not engage enemy surface forces. Despite their heavy losses, the British now had enough forces available to keep up the pressure, and Coire and Comhcheangal were frequently employed as escort flagships for troop and supply convoys between Thiaria and the South American mainland. Coire came twice under air attack by British raiding forces in the second half of 1943, Comhcheangal thrice; both were twice attacked by enemy submarines as well. One submarine attack resulted in Coire's loss in December 1943 to three torpedo hits from HM Submarine Tradewind. Comhcheangal at that time was under refit, receiving modernized radars and eight more 20mm guns (swapping the single mounts with twins); she re-entered service in January 1944, looking like this:
Assigned to convoy escort duty, she was at sea during the battle of Anfa Caolas, but belonged to the close cover group of the convoy the Allies were attacking, and made it safely to Montevideo. Though victorious, the Thiarians were decisively weakened and not able to deploy a fleet against the allied invasion of New Portugal, which eventually was launched less than two weeks later. With land-based air cover from New Portugal no longer available, supply convoys to Monteviedo to keep the Thiarian army in Brazil in business became more and more hazardous, and on June 22nd, a strong British fleet nearly annihilated a particularly large Thiarian convoy. Three escort carriers and many transports were lost, and Comhcheangal was damaged by two 250kg bomb hits. Although the damage was initially judged to be not very severe, she ran into bad weather, suffered additional storm damage and reached Montevideo with her bow totally awash. She received emergency repairs there, but could not be declared seaworthy before the Thiarian army in Uruguay surrendered to the US on October 4th. As the Thiarian forces in Uruguay were interned, Comhcheangal was seized by US forces. She was not beyond economic repair - a well equipped dockyard could have brought her back on line within six weeks - but considered a constructive total loss anyway by the Americans and not handed over to the co-belligerent Thiarian forces. She remained moored some kilometers into the River Plate for three years until her fate was decided in the peace treaty of 1948. She was ceded to Brazil as a reparation, but by that time, she was a hopeless case. She was towed to Rio de Janeiro, surveyed, declared structurally unsound, and scrapped in 1950.
