Spaces can be rapidly and simply used for HADRO through to war fighting operations, with volume spaces able to accommodate role-specific equipment in a modular form. The ability to fit the existing systems and equipment from the parent design is retained to provide flexibility in the capability supplied at build and through the life of the platform.
The platform will operate in all states and conditions with a Ship’s Company of less than 100 personnel. With dedicated accommodation for 160+ personnel and additional temporary accommodation, the platform can carry a significant number of Embarked Military Force, including Special Forces, littoral manoeuvre troops or additional command and control personnel.
Accommodation for Medium Calibre Gun options up to 5” (127mm) for maritime interdiction, self-protection and engagement of surface and land targets. Small Calibre Guns up to 40mm calibre can be located in predesignated upper-deck weapon positions. Capability options include Provision for up to 8 canister-launched SSGW; VL missiles (SAM/SSGW/Land Strike/ASW) up to 32 cells, and Close-In Weapons Systems.
Strike Length silo can be fitted to incorporate a combination of a larger number of anti-air missiles, vertical launch antisurface missiles, precision land strike missiles or ASW weapons such as ASROC. This particular adaptability feature, alongside the ability to install a 127mm (5”) medium calibre gun, host an organic helicopter such as AW-101 Merlin, install sensors such as a towed array/variable depth sonar and re-introduce a magazine-launched torpedo system, amongst other proven features, will allow the platform to be tailored on build and through-life to suit operational requirements from low-threat maritime security to warfighting in task group operations.
The layout of the design benefits from the experience of several years of real-world NATO and coalition operations, including integration within US Navy Carrier Strike Groups as an escort platform. These lessons learnt from the baseline design lead to key operational and mission areas within the Arrowhead 140 design that are situated to provide an optimal layout for operations in both peacetime and high threat operations. The key mission areas benefit from proximity to each other and protection through the relative location within the ship. Supportability of major equipment identified through shipping routes and space envelopes.
The propulsion arrangement is a proven and efficient CODAD architecture, already in service. This is demonstrated to provide a flexible speed range with 28+ knot maximum and 18 knot efficient cruising speeds, in a package with a low maintenance burden and consideration towards underwater radiated noise (URN) signature. The size of the platform allows sufficient fuel for long-range independent global operations. Space and systems configured for compliance with IMO Tier III regulations for ECAs.
Significant operational flexibility is inherent in a platform with the capacity of Arrowhead 140. Based on a proven NATO frigate design, with flexible spaces able to host disaster relief stores or civilians during evacuation operations among other roles; a demonstrated capability already employed within the in-service design.
