UK MSAMs
The wonder is not that UK now has no MSAM, but that in 1949 UK funded 3.
The pits of life for W.Europe was after the Berlin Airlift (over, 30/9/49), before 26/6/50 outbreak of the Korean dress rehearsal for WW3. Though NATO - d'Artagnan: all for one, one for all - became visible as uniforms in SHAPE/Paris 24/8/49, there was nothing tangible to keep US in, Germany down, Russia out. Yet we then diverted resources of one of few UK industries making things of $-earning value: electronauts GEC/Marconi/Ferranti/Cossor/EKCO...from brown goods (radiograms) to GW...on Seaslug and on (to be) Thunderbird and Bloodhound.
Ministers eased the Task with Burns/Templer Data Exchange (!Ha!?) Agreements 2/50, accessing i.a propulsion and aero-controls for Bloodhound. But US, then and later, offered licence deals for Sparrow AAM, Nike/Ajax land- , Terrier marine-SAMs. Ministers rejected all - yes, the same suits so traduced by many Aero-scribes as being anti-Aero: Terrier was declined 7/51 due to “bad effect (on UK) GW industry” S.R.Twigge,Early Devt of GW in UK,’40-60, Harewood, 1993, P.164 plus uncertainty US “would supply” E.J.Grove,Vanguard to Trident, Bodley Head,1987,P121. But Ministers chopped and changed priorities in funding and resources allocation: Seaslug, for example, slimed between equal-highest and no priority vs. Bomb/Bombers and their base defenders, so no Capability was derived from any of the 3 until 1960-62.
MIM-23 Hawk, funded 1952, deployed 1959, was sold to every friendly-body, built by NATO Consortium SETEL to 1971 (HSD repaired them for years), in Japan to 1978. Including MIM-23B Improved Hawk, >40,000 rounds, some still with a dozen Users in 2012...ah, well, now we have MOTS.
