Subject: AS90 upgrades
perfectgeneral    2/1/2005 8:11:15 AM
The 52 calibre upgrade (from 39) for non-Braveheart AS90's has been put on hold. UK land forces fall behind once more in force concentration. Maybe we will eventually see a better upgrade as a result of this? 1500 hp power plant? 155mm/55 calibre up-gun? Barrel cooling system? The wish list is endless I suppose. Light and medium forces seem to be flavour of the month, so will we see a medium artillery system like the isreali SPWH 2052 truck mounted howitzer? Could that be a 155/55? Given that mobility would be it's main protection a 1500 hp power plant would help (some common spares with the C2 MBT would help too).

Interesting recent report on 105mm L118 that may flow thru to AS90. LINAPS is being modified to display the data from Marcal (the MV radar fitted to every UK gun) obviously this reduces overall power consumption by removing a disply. However, they are also going to feed the round to round MVs from Marcal into LINAPS and use it to adjust the firing data by applying MV prediction for the next round (UK developed and proved methods for this some 15 years ago). The next step would be to use LINAPS to do the ballistic calculations, but the issue seems to be that LINAPS already has a ballistics program but its proprietary, non NABK, not approved by the ordnance safety people and proably not developed in accordance with UK requirements for safety critical software. No doubt BAe and LogicaCMG will sort it out between them.
