Can anyone tell me if they ever did a live fire of a Genie missile? Were there any drones involved?

Can anyone tell me if they ever did a live fire of a Genie missile? Were there any drones involved? Ed Yes. But by an F-89. A live Genie was detonated only once, in Operation Plumbbob on 19 July 1957. It was fired by AF Captain Eric William Hutchison flying a F-89J over Yucca Flats at an altitude of 4,500 m (15,000 ft). A group of five USAF officers volunteered to stand hatless in their light summer uniforms underneath the blast to prove that the weapon was safe for use over populated areas. They were photographed by George Yoshitake who stood there with them. Gamma and neutron doses received by observers on the ground were negligible. Doses received by aircrew were highest for the fliers assigned to penetrate the airburst cloud ten minutes after explosion. Mark

AIR 2As were live fired all the time at Tyndal but without the nuclear warhead. Every six squadron had to do annual live fire qualification of its aircraft shooting a Genie against a Firebee drone. If I remember correctly there were five kill radius around the target in 500' increments. An area 5 kill (2500 ft from target) would qualify the aircraft.
Note. It wasn't an Air Intercept Missile (AIM), which meant it was guided (manuever to target). It was an Air Intercept Rocket (AIR), meaing unguided (point and shoot).

Recently I made a search about the Air 2 Genie on this website: www.aereimilitari.org/forum/index.php?showtopic=11932 I would like to share with you my calculation. The launch parameters of the Genie obliged the interceptor’s pilot to a hard manoeuvre to escape from the shock wave of the nuclear blast. The pilot had less then 10 seconds to roll inverted, dive and escape in the opposite direction. Some sources often report a 1000 ft blast kill radius. Some other say 1 cubic mile. So, I decided to calculate the real effect of a Genie’s warhead. The W25 reached 1.7 Kt. Nine times less than Hiroshima’s blast (15 Kt) that destroyed brick walls within 1.5 miles radius, caused minor demages within 2.5 miles and broke glass till 8 miles. Unfortunately for the “red force”, the bombers are much more fragile then bricks. During nuclear blasts in the Nevada test site, the target aircrafts were heavily damaged with 1.5 PSI only ! Genie’s warhead was theoretically able to blow up a bomber within 1000 ft and to destroy within 0.5 miles radius. But the shockwave will damage heavily the aircraft within a miles radius, breaking part of wing, ailerons, propellers, pylons, glass cockpits and causing flameout in the engines. Till 4 miles radius the 0.5 PSI over-pressure will damage the glass cockpit causing decompression. Thermal flash: the fireball will have a 120 ft radius (0.3 seconds flash-time). Within 600-1000 ft will melt the light metal. Within 0.5 miles will cause 3rd degree skinburn, will light the rubber and will melt the plastic material or plexiglass. It will blind the pilots for some miles. EMP effect: over 5 miles radius every electronic material like radio, radar, weapon fuzes and so on, will be broken or damaged. Only valve-based electronic maybe will survive. Last but not least, radiation. Letal within 0.5 miles radius. So, even if the enemy bomber will escape, it ‘ll be forced to stop the mission and, probably, it will have a crash in the next few minutes…

Before it was the AIR 2A Genie, it was th MB-1 Ding Dong. Lethal blast radius was approximately 1,000 ft, but the shock wave could extend significantly further depending on atmospheric conditions. Rocket range was around 6 miles, so radical escape manuevers were authorized. The F-106 -1 Flight Manual (unclassified) cautioned the pilot to focus on the instrument panel during escape in order to avoid flash blindness; and to also avoid exceeding 4 g's.

I was wrong ! Many years ago I calculated the effects of an AIR-2 Genie. But the numbers were correct for a very low altitude explosion, very unlikely... First of all: at high altitude there is no Mach stem, no reflection of the blast wave on the surface. Second, more important: at high altitude, say... 35000 feet, the atmospheric density is only 1/3 of that on sea level, and the blast pressure is directly proportional to the density. So, I will have to revise the calculations. The radius of the EMP, of the thermal wave, of the radiation are, also, very different. I will write the new data here, when I will finish an article on the nuclear weapons.

If memory serves, it doesn't take that much overpressure to break a Bear's back. Not sure how the math changes with Blinders, Backfires or Blackjacks and their different wing loadings, though. Takes a big man to admit an even if it's been years since and few likely to see it anymore... much respect for that, sir.
