The '''Néamhann-class destroyer''' is a type of {{wp|guided missile destroyer}} designed and manufactured in [[Tír Glas]]. Whilst the class is as a whole orientated towards the roles of {{wp|Anti-aircraft_warfare|anti-aircraft warfare}} and {{wp|missile defence}}, there are distinct differences within the class such as, the Batch 2 vessels, which were built around an improved {{wp|anti-submarine warfare}} system or the Batch 3 vessels which were built with larger command and control facilities to act as {{wp|flotilla leader|flotilla leaders}}.<br>

The '''Gemstone-class destroyer''' is a type of {{wp|guided missile destroyer}} designed and manufactured in [[Tol Galen]] to replace a variety of ageing classes. Whilst the class is orientated towards the role of {{wp|Anti-aircraft_warfare|anti-aircraft warfare}} and {{wp|missile defence}}, there are distinct variations within the class such as, the Batch 2 boats which are dedicated {{wp|anti-submarine warfare}} platforms or the Batch 3 and 4 boats that are operated as {{wp|flotilla leader|flotilla leaders}}.<br>
+
The néamhainn were built to replace the a variety of ageing classes of destroyers and frigates, initially it was intended for there to be forty vessels constructed, this was however reduced to thirty on the basis of quality over quantity. There were to have been six follow-on vessels constructed which would have formed Batch 4, these vessels would have differed from earlier vessels with the substitution of {{wp|SAMPSON}} for {{wp|https://en.wikipedia.org/wiki/CEA_Technologies|CEAFAR}} as well as minor structural improvements. These were however rejected in favour of a modified {{wp|Iver_Huitfeldt-class_frigate|Iver Huitfeldt}} class

Tol Galen had sought to procure a new class of destroyers in collaboration with several other GA nations under the GFR-90 project; however, the varying requirements of the different countries led to the project being abandoned in the early 1990s. Tol Galen then joined New Tyran, France and Italy in the development of the {{wp|Horizon-class_frigate|Horizon-class}} frigate; however, the souring of relations between the Global Alliance and Able Vigil Accords as well as differing requirements to those of New Tyran, led to the both Tol Galen and New Tyran withdrawing on 26 April 1999 and starting their own own projects. Initially Tol Galen had partnered with New Tyran to procure what would end up as the {{wp|Type_45_Destroyer|Type 45}}, disagreements over work-share and technology transfer led to the partnership dissolving in mid-2001. Several companies tendered designs between 2002 and 2004 with Lynch & Murphy offering a modified version of an existing design that they had been offering to various nations since the late 1990s. It would be this design that the Galenic Government chose for what would come to be known as the Gemstone-class.

The Gemstones are 155m in length, with a beam of 20m, a draught of 5.3m and a displacement of approximately 7,100tonnes. This makes them significantly larger in all dimensions than any of their predecessors. The design of the Gemstone-class brought with it higher levels of radar and infra-red signature reduction to the Royal Galenic Navy. Deck equipment and life rafts were concealed behind the ship's superstructure panels and panelled railings where possible leading to a very "clean" look when compared to previous vessels.

The Gemstones are noteworthy for being as far as feasibly possible gender-neutral with living spaces tailored to accommodate both male and female crew members. Communal sanitary facilities have given way to individual cubicles, cabins for junior ratings are now far more flexible enabling the accommodation of a mixture of male and female sailors.

The Néamhann-class destroyer is a type of guided missile destroyer designed and manufactured in Tír Glas. Whilst the class is as a whole orientated towards the roles of anti-aircraft warfare and missile defence, there are distinct differences within the class such as, the Batch 2 vessels, which were built around an improved anti-submarine warfare system or the Batch 3 vessels which were built with larger command and control facilities to act as flotilla leaders.
The néamhainn were built to replace the a variety of ageing classes of destroyers and frigates, initially it was intended for there to be forty vessels constructed, this was however reduced to thirty on the basis of quality over quantity. There were to have been six follow-on vessels constructed which would have formed Batch 4, these vessels would have differed from earlier vessels with the substitution of SAMPSON for CEAFAR as well as minor structural improvements. These were however rejected in favour of a modified Iver Huitfeldt class

Origins

The initial origins of what would become the Néamhann family started at a time of heightened tensions In the Meridian Ocean. Tír Glas had sought to procure a new class of destroyers in collaboration with several other GA nations under the GFR-90 project; however, the varying requirements of the different countries led to the project being abandoned in the early 1990s. Tír Glas then joined New Tyran, France and Italy in the development of the Horizon-class frigate; however, the souring of relations between the Global Alliance and Able Vigil Accords as well as differing requirements to those of New Tyran, led to the both Tír Glas and New Tyran withdrawing on 26 April 1999 and starting their own own projects. Initially Tír Glas had partnered with New Tyran to procure what would end up as the Type 45, disagreements over work-share and technology transfer led to the partnership dissolving in mid-2001. Several companies tendered designs between 2002 and 2004 with Lynch & Murphy offering a modified version of an existing design that they had been offering to various nations since the late 1990s. It would be this design that the Glasic Government chose for what would come to be known as the Néamhann-class.

Characteristics

The néamhainn are 155m in length, with a beam of 20m, a draught of 5.3m and a displacement of approximately 7,100tonnes. This makes them significantly larger in all dimensions than any of their predecessors. The design of the Néamhann-class brought with it higher levels of radar and infra-red signature reduction to the Royal Glasic Navy. Deck equipment and life rafts were concealed behind the ship's superstructure panels and panelled railings where possible leading to a very "clean" look when compared to previous vessels.

The néamhainn are noteworthy for being as far as feasibly possible gender-neutral with living spaces tailored to accommodate both male and female crew members. Communal sanitary facilities have given way to individual cubicles, cabins for junior ratings are now far more flexible enabling the accommodation of a mixture of male and female sailors.

Capabilities

Anti-Air warfare

PAAMS

The Batch 1 and 1A néamhainn are equipped with a variant of the PAAMS system (SAMPSON and S-1850M), unlike the existing PAAMS system the system used by the Royal Glasic Navy utilises CEAMOUNT phased-array directors to provide guidance for Sea Sparrow and Standard missiles.

LAMS

The Batch 2 and 3 néamhainn are equipped with a scaled back air-defence system more suited for the local and self-defence role. Like the Batch 1 and 1A vessels they utilise SAMPSON and CEAMOUNT but unlike the Batch 1 and 1A vessels they lack the volume-search radar.

GAAWS

The Batch 4 néamhainn would have been equipped with an octagonal mast structure bristling with arrays for the CEAFAR family of radars, they feature arrays in X, S and L-band as well as a VHF/UHF communications system, ESM and surveillance systems. The Batch 4 vessels were seen as being mid-way in capability between the Batch 1 and Batch 3 vessels with greater anti-aircraft warfare capabilities than those vessels lacking the large volume-search radar but still somewhat behind those equipped with it.

Batches Compared

  • Batch 1 and 1A: SAMPSON Multi-Function Radar (MFR) and S-1850M Volume Search Radar (VSR).
  • Batch 2 and 3: SAMPSON Multi-Function Radar (MFR).
  • Batches 1 through 3: Sharpeye S navigation, surface-search and helicopter-control radar.
  • Batch 4: CEAFAR2-X, CEAFAR2-S, CEAFAR2-L Multi-Function Radars (MFR)

Guns

Main Gun

All vessels built thus far have been equipped with variants of the Mk 45 127mm gun, initially in its 54-calibre form, and more recently its 62-calibre one. Those vessels initially fitted with a 54-calibre gun have been retrofitted with the longer gun during light refits.

CIWS

All vessels built thus far have been equipped with the 30mm SAMOS gun/missile CIWS. Batch 2 and 3 vessels were initially completed with only one mount atop their hangar due to budgetary constraints but have since been fitted with their forward mounts. The SAMOS mounts themselves have undergone considerable changes since entering service including, improvements to their fire-control sensors and improvements to their guns. They have been qualified to fire Starstreak, Starburst and Martlet with qualification of a 70mm MHTK derivative under-way.

Batches Compared

  • Batches 1 through 4: 1x Mk 45 Mod 4 (HE-PD, HE-PFF (FREMEN 127 Fuze), Excalibur N5 and HVP)
  • Batches 1 through 4: 2x SAMOS gun/missile CIWS, 4x MSI Seahawk Lightweight RWS (20mm)

Missiles

All vessels built thus far are equipped with a block of 64x strike-length P82 cells forward and 16 self-defence length P82 cells amidships.

Usual Missile Complements

Whilst operational requirements dictate the actual makeup of a vessel's ordnance, there are standard operational outfits which are:

Area Air Defence

  • 8x Mosquito surface-to-surface missiles
  • 6x Sea Lance anti-submarine missiles
  • 4x SM-3 Block IIA anti-ballistic missiles
  • 4x SM-6 extended-range surface-to-air missiles

Aviation

On-board Facilities

Both the Batch 1 and 1a vessels have hangar and maintenance spaces suited to the operation of a single Strikehawk plus a flexible number of unmanned aerial systems (UAS) whilst the more general-purpose Batch 2, 3 and 4 vessels feature a revised hangar layout capable of accommodating a pair of Wildcats plus UAS. The flight-deck is equipped with an Aircraft Ship Integrated Secure and Traverse (ASIST) system for safer recoveries with tram-lines to the hangar bay. All vessels feature a workshop to carry out basic level maintenance on their embarked aircraft.

UAVs

The Néamhann-class were always envisaged to be capable of operating some form of unmanned system although at the time of their construction no such system had been procured. Currently there are a three systems qualified for use on the class, these are:

  • ScanEagle long-endurance surveillance UAS
  • Camcopter S-100 rotary-wing surveillance UAS
  • Fire Scout (Development is ongoing on a locally-produced derivative using the Fire Scout architecture but based on a Bell 427)

Optical Sensors

The Néamhann-class are equipped with a variety of optical sensors. Common to all vessels are:

  • 4x Silent Watch-derivedsurveillance systems
  • 2x SeaFLIR 380-HLD Fire-Control Systems
  • 1x SeaFLIR 230 for helicopter operations

Countermeasures

Countermeasure Dispensers

The Néamhann-class are equipped with a pair of Centurion revolving countermeasure dispensers capable of deploying a variety of countermeasures and weapons. They are usually equipped with three to four types of decoy / countermeasures which are:

  • CHIMERA Mk.4 (Dual-Mode IR/RF Decoy)
  • Seagnat 214 (RF Seduction Decoy)
  • TALOS (Infrared and EO/Laser Decoy)
  • PIRATE (Infrared Seduction Decoys)

Electronic Warfare

All of the néamhainn are also equipped with a pair of multi-face NOLQ-2-derived ECM/ESM systems capable of both ELINT and defensive-jamming. In addition, all néamhainn are fitted with the Vigile-DPX ESM system. Addionally all néamhainn feature an optical (infra-red and ultraviolet spectrum) missile warning and countermeasures system on their mast-heads.

Communications and Other Systems

The néamhainn are all fitted with a derivative of the Thales FICS system with:

Tactical Data Links:

  • TCDL
  • Link 11
  • Link 22
  • Link 16
