That's the thing.....MLRS was a joint programme in the past. It started as GSRS and was a US/West Germany/France and UK joint programme. European countries built M270 and also made rockets, including their own specialist payloads (AT2). The UK also jointly funded GMLRS with the US...Europe has also made its own launch vehicles (LIMAWS(R)) and fire control (LRU/Mars/-I) in the past.
Restoring that Jointness would have benefits to all sides....if Europe had its s**t together they could have approached the US and given them a take it or leave it offer....make MFOM and Fire Control 'open source' or we build our own equivalent European system with our own payloads. The benefits to all sides of that arrangement are pretty obvious...
Absolutely. We could have had M270A2, HIMARS, GMARS, LIMAWS(R) and Foudre covering all possible bases and in use with all NATO militaries....US would probably still make the bulk of the money with GMLRS, GMLRS-ER and PrSM. But adding in JFS-M, LPS, Thundart etc would make it an even more compelling system.
