Other upgrades for Typhoon are ongoing, BAE are to perform more Meteor live firings in August and are to fly a developmental AESA radar on an aircraft during the third quarter. Alenia Aermacchi are to perform Storm Shadow separation trials in September.
No word yet on Brimstone 2, but considering it's a UK weapon it'll be done by UK companies I guess because unlike Storm Shadow there's no similar European equivalent (like Germany and Taurus for example). But that, Storm Shadow and Meteor are to become available in 2018 as part of P2E enhancements.
The article further goes on to explain that there's talk of slowing down Typhoon production to maintain the possibility of further orders from Saudi Arabia, the UAE or Qatar. Current orders and production means the end of the line is late 2017/early 2018.
