JSOW Block II

The JSOW Block II weapon is being developed to significantly lower the production unit cost and offer an additional payload. Component parts amount will be reduced and the manufacturing process will be optimized to reach that goal. The development completion of the JSOW Block II, sponsored by the US Navy Air Systems Command, is planned in early 2006. In addition, the JSOW Block II will introduce RAPTOR anti-jam GPS receiver, Selective Availability Anti-Spoofing Module (SAASM), for enhanced survivability. SAASM integration contract on the JSOW Block II was awarded in early 2005. All variants of JSOW from 2006 will be manufactured in the Block II configuration benefiting from all its enhancements. First delivery of Block II weapons are planned in 2007. A new variant of JSOW A model carrying a new payload is now under development that could be available from 2006. The new JSOW A version will use a 500-pound (250 kilograms) BLU-111 unitary warhead instead of cluster munitions while elimination the unexploded sub-munitions concerns. It is aimed at the international market. Other JSOW improvements are under way to add anti-ship capability, reduce unexploded ordnance concerns, hit moving targets, provide bomb hit indication, provide network capability and further reduce costs.
