An ASW frigate can go on patrol/ policing/ antiterror duties whereas for a GP frigate to do ASW...
LMM ISD is very close (haven't seen any announcement), but more interesting in the above context will be its heavier brother, the details for which include
- during flight control (if boghammers are weaving amongst other shipping on busy shipping lanes)
- land strike, most interestingly laser designation by other parties (SF team on land?) so that the Wildcat does not need line-of-sight to the target:
"The AW159 Wildcat will be able to carry up to four launchers, two per weapon carrier, each with up to five LMM missiles, or up to four FASGW(H)/ANL missiles with two on each weapon carrier. [It will also be able to carry a mixed load of LMM launchers and FASGW(H)/ANL missiles for maximum mission flexibility... whenever that will be]
The MBDA FASGW(Heavy)/ANL features a high speed, two-way data-link that communicates the images “seen” by the missile’s seeker to the operator, who, in addition to initiating an autonomous engagement, can alternatively remain in control of the missile throughout the full duration of its flight. This optional, man in the loop monitor and control facility enables new capabilities such as: in-flight re-targeting; final aim point correction and refinement; and safe abort. Ultimately, the missile will be able to engage targets situated out of direct line of sight when the launch platform is able to benefit from third party target designation or laser illumination.
The Thales LMM is a lightweight, precision strike, missile that has been designed to provide a rapid reaction to a wide range of surface naval threats from small ships and fast inshore attack craft as well as on-land surface threats."
