I have tried looking on the internet for MASC related information - and have not found much. It appears to not be mentioned much on either the RN or MOD websites.
Back in 1990 there was a publication called Firepower, and one edition was about a carrier air wing. It made the point that although the E2 Hawkeye might not seem as glamorous as the F14, F18 et al it was probably the most important aircraft carried. In the digital age, with things such as CEC, that is more obvious.
Therefore MASC is key to achieving information superiority. However, it would seem that it has not received the attention from the MOD or parliamentary scrutiny it deserves. Why not?
