Jane's:
"The UK is said so far to have been unique in pursuing the Battlefield Target Identification Device (BTID) in a fast-jet air-ground operations context. A preliminary study conducted by TME in 2000-01 concluded there would be no 'show-stoppers' preventing the incorporation of a BTID interrogator in an airborne targeting pod.
BAE Systems has since been awarded a feasibility study contract, addressing matters such as antenna integration and Doppler effects, as a potential enhancement to the multinational ASTRID (Airborne System for Target Recognition, Identification and Designation) pod development program, which in the UK's case is intended to lead to a replacement for the in-service TIALD system. In 2001 the UK allocated £91 million to cover the ASTRID concept phase through to integration into service of up to 40 systems from 2010."
So don't worry chaps, if ASTRID ever gets the go ahead, and enters service on time, and the upgrade is added to the baseline contract and not as a subsequent modification you only have 7 years to wait. I'm sure nothing will happen between now and then.
Won't help with A-10s of course since, as stated, the UK is unique in going down this path.
