After much discussion, a decision was made that the
A-12s would be retired. However, in 1967 their capabilities were required in
the Vietnam War. Since the Air Force’s SR-71s were not yet qualified for
operational use, three A-12s were deployed to Kadena, Japan, in an operation
called BLACK SHIELD.
On 31 May 1967 Agency pilot Mel Vojvodich flew the first mission
to photograph North Vietnam.
My panel lit up with ECM gear and I knew they were gonna have a
launch. They started launching SAMs ninety miles away. I could see ‘em
coming up. They were passing on the control down the different battalions to try to knock me out of the sky. The only way they could ever get
an SR [sic] was to shoot way out in front of us.
Anyhow, many of them came up and you know, I’m not used to flying
straight and level. I’m a fighter pilot and it’s harder ’n hell for me to sit
there, even at 85,000 feet and Mach 3.2 and some bastard’s shootin’
missiles at me.
I had the biggest urge to want to make a hard turn and get the hell out
of there. But, I remember Slater [Col. Hugh ‘Slip’ Slater] said, “Now,
just trust your ECM gear Mel, it’s gonna work” and I’m sitting there
saying “Yeah, I wonder why HE isn’t here.”
Anyway, it’s kind of shaking to look at these missiles coming up
through about 50,000 feet in con. They fi red 24 at a time, coming up like
this. I could see ‘em coming up and they went underneath the belly of the
aircraft and I had to look through my view periscope and I could see ‘em
go behind me and they were up over 90,000 feet and they came down and
tried to track and by that time they had burned out and they’d detonate
behind the aircraft and had never even gotten close.
d. The radar cross section of the two aircraft in
a clean configuration is relatively low for both the S R -71 and
the A-12. The SR-71 in its full sensor configuration is somewhat
higher due to its larger size and appreciably larger with the
side-looking radar antenna installed, but this will not increase
vulnerability to the S-Band, SA-2 significantly, providing
installed ECM systems are utilized. Based on simulator test
results, it appears that the probability of kill in North Vietnam
is nil for either aircraft with presently utilized configurations
and flight profiles, as long as the ECM techniques used remain
viable. In any event, if it should be concluded that the radar
cross section is too hi'gh for any particular operation, the
side-looking radar can be removed from the SR-71; the same
limitations wotild apply to optional use of a side-looking radar
on the A-12.The SR-71 will be equipped with CFAX, APR 27 and System 13C. (See note 3 on "ECM Equipment" chart.)The A-12 is configured with 3 EWS systems (PIN PEG, BLUE DOG and either BIG BLAST or MAD MOTH) without removal of other sensors.
Configuration with three systems provides redundancy should failure
occur in any system.
current OXCART vulnerability are: The increased launch
range capability of the DRV SA-2 system launch in low
PRF will definitely increase kill probability under
conditions of OXCART jammer malfunction. The capability
agains-t the vehicle with fully operational ECM systems
is still considered to be essentially zero.
Начальством это было воспринято с инженерным пониманием — метод наведения на цель ракеты, применяющей активные помехи, именно для этой системы и именно для этой скоростной высотной цели не тянет (большие динамические ошибки, попросту говоря, ракета не вытягивает нужного); вдобавок боевая часть ракеты и радиовзрыватель разрабатывались под совсем другие самолеты — тихоходные “сейбры” и “суперсейбры”.
а приведенная вами табличка показывает лишь яркость цели на радаре и соответственно дальность обнаружения.
