The Gemstone-class destroyer is a type of 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 anti-aircraft warfare and missile defence, there are distinct variations within the class such as, the Batch 2 boats which are dedicated anti-submarine warfare platforms or the Batch 3 and 4 boats that are operated as flotilla leaders.
The Gemstones 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 have been four follow-on vessels constructed which form Batch 4, these vessels differ from earlier vessels with the substitution of SAMPSON for CEAFAR as well as minor structural improvements.
Contents
Origins
The initial origins of what would become the Gemstone family started at a time of heightened tensions with the FSR. 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 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 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.
Characteristics
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.
Capabilities
Anti-Air warfare
PAAMS
The Batch 1 and 1A Gemstones are equipped with a variant of the PAAMS system (SAMPSON and S-1850M), unlike the existing PAAMS system the system used by the Royal Galenic Navy utilises CEAMOUNT phased-array directors to provide guidance for Sea Sparrow and Standard missiles.
LAMS
The Batch 2 and 3 Gemstones 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 Gemstones are 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 are 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
Different Guns For Different Roles
The Tranche 1 and 1A Gemstones being orientated towards anti-aircraft and anti-missile warfare are equipped with a fast-firing Oto Melara 76mm gun (recently upgraded to fire DART and VULCANO guided munitions). The Tranche 2 and 3 Gemstones are equipped with a larger and more general purpose Oto Melara 127mm gun more suited to the naval gunfire support role. (again recently upgraded to fire VULCANO)
Tranches Compared
- Tranches 1 and 1A: 1x Oto Melara 76mm/62 Strales [HE-PD, HE-PFF (FREMEN Fuze), Vulcano and DART]
- Tranches 2 and 3: 1x Oto Melera 127mm/64 LW [HE-PD, HE-PFF (FREMEN Fuze)and Vulcano]
- All tranches: 2x Rheinmetall Millennium 35mm CIWS, 2x MSI Seahawk Lightweight RWS (27mm)and 2x Kongsberg Sea Protector RWS(12.7mm)
Aviation
On-board Facilities
Both the tranche 1 and 1a vessels have hangar and maintenance spaces suited to the operation of a single helicopter plus a flexible number of unmanned aerial systems (UAS) whilst the more general-purpose Tranche 2 and 3 vessels feature a revised hangar layout capable of accommodating a pair of small to medium helicopters plus UAS. The flight-deck is equipped with an Aircraft Ship Integrated Secure and Traverse (ASIST) system for safer recoveries with tramlines to the hangar bay. All vessels feature a workshop to carry out basic level maintenance on their embarked aircraft.
Helicopters
The Gemstones usually can be found operating with one of two types of helicopter. The AgustaWestland AW101 Merlin or the AgustaWestland AW159 Wildcat. The Tranche 1 and 1A vessels can embark one of either type whilst the Tranche 2 and 3 vessels can embark either one Merlin or two Wildcats. Other types are qualified to operate from the Gemstones with some degree of integration, those most often employed are the helicopters of the Royal Galenic Marines which comprise of suitably equipped AW101s and AW159s.
UAVs
Unmanned systems are still on the rise both worldwide and in Tol Galen. The Gemstones were always envisaged to be capable of operating some form of unmanned systems although at the time of their construction no such system had been procured. Currently there are a few systems able to be employed from the Gemstone class (all tranches), these are:
- Boeing Insitu ScanEagle long-endurance surveillance UAS
- Schiebel Camcopter S-100 rotary-wing surveillance UAS
- Northrop Grumman MQ-8C Fire Scout (Development ongoing on a local system using the same architecture based on a Bell 407T - Twin Engine Helicopter)
Sensors
All of the Gemstone-class are equipped with a myriad of sensors, both optical and infrared.
Optical
- 4x Thales Gatekeeper EO Surveillance systems
- 2x Thales Mirador EO Fire-Control Systems
- 2x FLIR Systems SeaFLIR 380-HLD Fire-Control Systems, (laser-designation of Griffon etc).
- 1x FLIR Systems SEAFLIR 230 for helicopter operations
Anti-Ship - Anti-Submarine and Land-Attack
All Gemstone-class are always to be found with at-least eight Tsetse Fly missiles which form the staple anti-shipping and land-attack capability. Between the various tranches there are a variety of different systems in use to fulfil the requirements of Anti-Ship - Anti-Submarine and Land-Attack warfare.

Countermeasures
Countermeasure Dispensers
All the Gemstones are equipped with a pair of Chemring Centurion revolving countermeasure dispensers capable of deploying a variety of both 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)
The Centurion as mentioned is also capable of deploying offensive systems, those currently in use include Griffin, and CRV7-PG.
Electronic Countermeasures
All of the gemstones are also equipped with a pair of twin-face SLY-2 type EW/ECM systems capable of both ELINT as well as defensive jamming.
Communications and Other Systems
The Gemstones are all fitted with a Selex Fully Integrated Communications System (FICS) with:
- Tactical Data Links: TCDL, Link 11, Link 22 and Link 16
- Satellite Communications: 2x Fixed EHF SATCOM antennae, 2x Inmarsat SATCOM antennae, 2x L-Band (Galileo), 2x S-Band (METOC + COMMS) and 2x X-Band (Skynet)
- Whips + Verticals: 4x AS-5085/SR HF whips and 2x OE-538 multi-band masts, 4x generic UHF whips and 2x generic VHF whips
Additional Capabilities
Flagship Capabilities
The Tranche 3 vessels are outfitted with extra command facilities to operate as flotilla or task group leaders. Usually this means that they are paired off with CVGNs or LPHs.
Embarked Military Force
All Gemstones are capable of embarking a platoon (30-40) of Royal Galenic Marines for VBSS and coastal-assault operations.
Intelligence Gathering
The Tranche 1 and 1A vessels are equipped with Thales's Vigile system (400) a six-faced arrangement for ELINT/SIGINT, the Tranche 2 and 3 vessels add to this with an 18-40GhZ antenna atop the hangar structure. Additionally the SLY-2 EW systems have an ELINT/SIGINT capability which is factored into the system.
