B-70 Paint scheme
Here is a good "what if" question. If the B-70 had gone into widespread SAC
use in the 60s and beyond, what is the best guess as to how it would have been painted for operational use? Black like the SR, white like the two XB models, gray, etc? I doubt it would have had the SAC cammo scheme, since it would not have done any low level flying. W. Woodruff |

The TBC (Toss Bomb Computer) settings for the weapon, airspeed, altitude, etc. included calculation for safe separation from the blast. When the aircraft were painted in camo for the SEA war, the entire nuclear delivery manual had to be re-calculated, because the dark paint absorbed the flash much more than the reflective bare metal. Greater safe separation distance was required. Frankly that scared the hell out of me. Hard to realize the whole business was calculated to such close tolerances. Ed Rasimus How much more distance did you need with the camo paint scheme? I remember watching F-4s heave practice bombs in Spain simulating nukes. I assume the nukes simulated, this was in the late 70s, were a bit smaller that 1 MT, but even so the F-4 seemed to not be very far away at time of detonation. Dan, U. S. Air Force, retired |

You're right. It wasn't just the strategic aircraft either. When I entered training for the F-105, the airplanes were still polished bare metal. The nuclear weapon of choice was the B-28 or B-43, each of them rated at 1 MT. Deliveries were usually programmed for some sort of low altitude low-angle toss with a wing-over escape maneuver to run away at about 135 degrees from original run-in heading.

Hi Scott
The RAF V-Bomber Force's high-level role changed in 1965 to a low level one. The Valiants, Victors and Vulcans were subsequently camouflaged from that point on. I was stationed at Goose Bay, Labrador when the transition took place. You've never seen anything prettier than a Vulcan flying at tree top-level. Especially when you are on a hill looking down on it!!!!!!!!!!!!! Cheers...Chris |

Always wondered what a camo B-58 might look like.

Tha Canadian CF104s that were tasked to the Nuclear Strike role in Germany
in the 1960s were bare aluminum except for the wings which were white.Teh cockpit had a special aluminized /retractible canopy shield and the pilot wore a gold-visored helmet. Ed, I am curious about the Bomb Toss computer in your a/c. We had a simple dual timer setup in the CF104. One clock was started at the run-in fix (or whatever it was called) and when it annunciated, the pilot performed the pitch-up/toss maneuver. At the appropriate time in this manuver the second timer went to zero and released the bomb. Seemed like a very simple (read cheap) system and I know the guys were often putting the 2,000 lb cement shaped charge within 100 mtrs of the dead centre on the range in Sardinia. Close enough with a nuke IMHO.Depending on the mission profile, the clocks were set to the appropriate number of seconds. Gary Watson ex RCAF "Ed Rasimus" wrote in message ...

Your Toss bombing computer sounds just like the one in the backseat of the
F-4 (it was built by my father while he was at GE). Quite interesting to fly with something my dad built. It worked well, so long as you had all the points plotted correctly and flew the planned airspeeds, altitudes and the pull was done to the proper g-load and onset rate. I have also done toss bombing using only the hack clock in the back seat, and gotten comparable scores. When you have to salvage a check ride you can think of lots of tricks. -- Les F-4C(WW),D,E,G(WW)/AC-130A/MC-130E EWO (ret) "Gary Watson" cf104@ihate spam.shaw.ca wrote in message news:dGw5b.591$J6.146@pd7tw3no...

One of my friends showed me a video of him in an F-16 dropping one of those Special shapes, from an F-16 at Tonapah. Did a 40 degree loft, got the bomb within 20 m.
