It was the mosquitoes that get me. One of 'em landed on the ramp at Patrick, and they put 1500 lbs. of JP-4 in it before they realized that it wasn't a helicopter. When I was stationed at King's Bay, the Simon Lake still had AA guns on either side of her stack - we used to tell the nubs they were for combating the mosquitoes. D. -- Touch-twice life. Eat. Drink.

Pat Yep, it is still there. I saw it a few weeks ago. You might be thinking of the new Atlas V pad having been built on top of the old Titan III/IV pad? Navaho XSM-64 flights lifted off from Launch Complex 9, which was a fairly massive concrete hard stand equipped with a big erector contraption. A big mobile hanger would roll over the top of the pad and erector when the erector was laid back horizontally with the booster and missile mounted on top. Complex 9 was south of the skid strip, just south of the fenceline of existing Launch Complex 31/32. A second, flat pad, Launch Complex 10, was also part of the Navaho site. Pad 10, which was never used for a launch, was located a bit north and east of Pad 9. During the early to mid 1950s, until it became clear that ballistic missiles could be made to work, Navaho was the nation's top priority missile effort - an effort that consumed more than $2 billion of today's dollars but produced no operational missile system. The money wasn't all wasted. Atlas development was eased by the already- available Navaho booster rocket engines, for example. Today's Delta II RS-27A will apparantly be the final descendent of the Navaho engine. Atlas, BTW, was launched from a completely different set of pads north of the skid strip, an area known as ICBM Row. The early Atlas launches occurred while the Navaho Complex was still active. It quickly became clear that Atlas was working and Navaho wasn't. Soon after Navaho was shut down, in 1958, Launch Complex 10 was bulldozed to make way for Minuteman Launch Complex 31/32. The Minuteman complex was oriented on a slightly different launch azimuth, so a small portion of the Navaho launch site remained outside the fence, including the massive Launch Complex 9 concrete hard stand that still stands next to an access road today. I did a writeup on this a few years ago, at: "http://www.geocities.com/launchreport/navaho1.html" Here is a 1999 aerial photo of the old Navaho pad, in the center of the oval concrete area: "http://www.terraserver.microsoft.com/image.aspx?T=1&S=10&Z=17&X=2715&Y=15736&W=1&qs=%7c cape+canaveral%7cfl%7c" The erector used to fold back to the east (right). The hanger used to roll back to the east as well. - Ed Kyle |

Yeah, I just dug out my Navaho book, and that's the set-up all right, I don't know where I got the idea that Complex 9 had been converted for Atlas work. There was a launch from the mobile launcher from Complex Ten though; after a lot of delays missile G-26 number four (S.N. 53-8271) riding booster number nine was launched on August 12th, 1957. The flight was intended to go to St. Lucia, but suffered control problems that caused its ramjets to fail one after the other only 7.5 minutes into the flight, and it crashed into deep water just off Great Abaco Island after only flying 230 miles. They had originally erected this missile at Complex Nine for launch, but it suffered one technical problem after another, so it was sent to be repaired, and then ended up at Complex Ten on the mobile launcher. There's an odd little mystery regarding missile G-26 number two; although it was launched from Complex Nine, Cape Canaveral records state that the missile was launched from Complex Ten.

The SINS used onboard SSBN's are a descendant of the Navaho guidance system - Though only one remains in service and is slated for replacement next year. D. -- Touch-twice life. Eat. Drink.

Gibson says that the second launch was originally planned to go from the mobile launcher at 10, but the plan was changed not long before the launch date, which might explain the garbled records (the Cape was very busy back then, with a launch every few days). There is a photo showing the second launch going from the fixed pad. - Ed Kyle |

It might have been considered semi-classified. That was a mighty big thing to be hauling around on a trailer. The booster exhaust blast out of the trailer exhaust deflector chutes would really have been something to see though.

I went looking on the web to see if I could find any photos of a launch from the mobile unit; I didn't find any, but I did find this photo of the aftereffects of launch attempt number three: https://www.patrick.af.mil/heritage/...s/12navwrz.jpg Pat |

That could crash fairly well also: http://www.astronautix.com/lvs/burya.htm Burya looked more primitive than Navaho, but I think they may have made a wise move with the nose intake; Navaho had a problem where a sharp turn could lead to one of the ramjets flaming out due to disturbed airflow over the fuselage going into the side intakes. The thing that looks like a canopy on the spine of Burya is the glazed quartz cover over the guidance system's star tracker; we obviously could do these a lot smaller than the Soviets could. What's interesting about Burya is that the March 7th, 1955, "Life Magazine" had an article about a rocket powered bomber that was supposed to be sled-launched like the Antipodal Bomber with the aid of two jettisonable underwing booster rockets. Although the Soviets did play around with a Antipodal Bomber knock-off, it was supposed to use wingtip ramjets, not rocket boosters. but the thing does look more than a little like a Burya lying on its side, and I always wondered if life had some leaked intelligence info that they were basing the article on. Real old-timers will remember mention of Soviet rockets in the 1950's before we knew much about them; the Life Magazine one portrays the T-4A winged missile in a manned form. The T-4 was supposed to be a souped-up far longer ranged V-2, and this is the Soviet variant of the A-9/Antipodal Bomber concept in a horizontally launched form. Pat |
