So this was intended to give both the Cobra and the Avenger an extra punch against ground and air targets. Interesting. Would I be overly paranoid in suspecting that it got killed by politics rather than technical issues?
Althought SPIKE is unguided, I thought this thread better suited to the Missile section. And we already
have several threads about unguided rockets or rocket systems here, like the Javelot.
Just in the same way, Bill Gunston did, in his "Encyclopedia of Rockets and Missiles" ..
Just the thing that interceptors needed back in the last days of the pre-missile era, when large volleys of unguided rockets were the only way forward beyond guns. Yes, a Zuni or a Mighty Mouse will blow the wing off a Soviet bomber and this will not; but given that so much of a modern military aircraft is full of critical things, it's not hard to imagine a cloud of those flechettes doing bad stuff inside - the Golden BB effect multiplied and pushed up to Mach 4 or so. And it would be a lot harder to miss.
