History
Launch Complex 15 originally broke ground in 1957, as part of an expansion by the United States Air Force to Missile Row, which would give it the ability to launch the HGM-25A Titan I alongside the four existing SM-65 Atlas pads. [3] LC-15 was built as the southernmost of the four Titan pads of the subsection, joined by LC-16, LC-19, and LC-20 to the north. The pad's construction saw its completion in summer 1958, and hosted its inaugural launch with the Titan I's maiden flight on February 6, 1959. [4] In this initial configuration, LC-15 hosted ten Titan I launches, all of them successful and being used for testing reentry vehicles as well as the missile itself. [5]
Following the last of the Titan I launches in September 1960, LC-15 underwent conversion to support the Titan I's successor, the LGM-25C Titan II. [4] Among the changes made was the replacing of fueling from the RP-1 and liquid oxygen used by the Titan I to the hypergolic propellants used by the Titan II. The first of these launches in this new configuration was made on June 7, 1962, and the pad subsequently saw a total of 16 suborbital launches throughout the following three years. One noteworthy launch from LC-15 during this era was on February 6, 1963, which featured the first all-Air Force-personnel launch of a Titan rocket, as well as being the heaviest payload ever to fly on a missile from the Eastern Range. [4] [5] The final Titan II launch to occur from the pad was conducted on April 9, 1964; following this, LC-15 remained semi-active until its official decommissioning in March 1967, with structures such as the blockhouse being used as office space by NASA. Later in the year, the pad was dismantled and the launch tower was sold for scraps.
For the next 50 years, LC-15 remained untouched and was abandoned in place. Structures such as the launch table and ramp remained standing, as did the blockhouse until it was demolished in 2012. [4] On March 7, 2023, the United States Space Force leased the pad to ABL Space Systems as part of a reactivation campaign made in the wake of the NewSpace boom of the 2010s, with the official announcement being made alongside the leasing of Launch Complex 14 (LC-14) to Stoke Space and Launch Complex 13 (LC-13) to Phantom Space and Vaya Space. [1] The same day, ABL announced that they planned to use LC-15 for the RS1 rocket, which was at the time being launched from the Pacific Spaceport Complex on Alaska's Kodiak Island. As the pad at the time of leasing was a brownfield for the past half-century, they also clarified that the rocket would temporarily make launches from Space Launch Complex 46 (SLC-46) while the LC-15 infrastructure was being built. [6]
In October 2024, following the accidental destruction of an RS1 to be used in the second flight, ABL announced that they would be leaving the commercial launch market in favor of perusing missile defense. [7] This was made official the next year, when they rebranded themselves as Long Wall, announcing that they will convert the RS1 into a target missile named the RSX. [2] It remains unknown what is to become of LC-15 as part of this change; although official Space Force documents continue to reference the pad as being leased by ABL, the limited pad availability at Cape Canaveral may entail that Space Launch Delta 45 is willing to lease it to another launch company.
