Launch Complex Highlights

31 August 1949 - Preliminary surveys for the launching area at Cape were completed. The blockhouse, launching pad, and 3,500-foot launch track areas had been staked and the area partially cleared.
February 1950 - Extensive clearing operations in the launching area began
9 May 1950 - Work started on Launch Complex 3 under a contract to Duval Engineering Company. ($258,000 for the concrete pad and a paved road (4.7 miles) from then highway A1A. Another $80,000 contract to Ingram Plumbing for a fire fighting water system
May 1950 to 15 June 1950 - The original wood frame firing room (20' x 20') was constructed about 400' from pad 3 for the Bumper launches. It was below ground level and had a window with reflective mirrors to view the pad
20 June 1950 - Pad 3 was reinforced concrete slab 100 x 100' and 8" thick and completed
5 September 1950 - The U.S. Army Corps of Engineers selected the contractors and construction started on Pad 4
30 November 1951 - The blockhouse, located about 200' from the pads and similar to that for Pads 1 and 2, was completed. Two mirrored vision ports, one direct vision port, and a ladder to the top of the roof provided a view of the pads.
Two concrete tunnels connect the blockhouse to the pads. They were 4' by 6'8" and 5'8" by 5'8" by 6'8".
March 1953 - The Air Force accepted the launch complex
1955 - High Pressure Air Building was constructed
August 1961 - Blockhouse was converted to serve as a dispensary for the manned spaceflight program and was vacated in 1967.
30 June 1950 - Initial erection and test of the Bumper gantry, a missile-working stand, was completed
24 July 1950 - Cape's first major launch was Bumper 8 from Launch Complex 3
29 July 1950 - Second and last Bumper-WAC launched from the Cape
25 October 1950 to 8 July 1953 - Total of 40 Lark missiles launched
5 September 1951 - Construction on Launch Complex 4 started. The pad is reinforced concrete 100' x 200' and 8" thick. Another area measuring 182' x 300' surrounding Pad 4 was paved
1952 - Air Force accepted Launch Complex 4
23 January 1953 to 30 November 1955 - Total of 16 Bomarc launched
11 February 1953 to 25 March 1953 - Four RV-A-10 launched from Pad 4
August 1953 - The Missile Service Stand (MSS) gantry was erected on Pad 4 for the Redstone missile. The MSS was built by Noble Company in California and erected at Pad 4. It was 135' high, 26' wide and 61' long and weighed 308,000 pounds. Designed to be mobile on railroad tracks, it had a 15 ton crane with 4 movable work platforms, an air conditioned work room, elevators and standby power plant
February 1955 - Missile Service Stand from Pad 4 was moved to Launch Complex 6
23 May 1955 to 11 December 1957 - Total of 51 X-17 launched
1955 to 1958 - Bomarc Launching Building (BLB), Launch Complex 4A, was constructed. The building was designed with a roof which would split in the center to allow raising the Bomarc missile for launch
2 February 1956 - First Bomarc launch from Launch Complex 4. Pad 4 had a prototype launch building, Launch Complex 4A, for the Bomarc missile that would be used throughout our country as a defense weapon system. Eight were launched from the Bomarc Launching Building.
2 February 1956 to 15 April 1960 - Total of 52 Bomarc A and B launched
