As the HARP program progressed, the political and financial environment would not allow full development of the Martlet 4, so a scaled down version of the Martlet 4 program was initiated -- the Martlet 2G-1. Also, by this time, the HARP program was entering its last six months of official life and had already started close-out operations, so time was of the essence. In order to demonstrate the orbital capability in the few months that remained, the simplified 2G-1 system was proposed. It was a novel approach suggested by Mr. C.J. Swet of the Applied Physics Laboratory of John Hopkins University. Though successful test firings were completed (as shown in fig 51c), the rapidly approaching close of the program did not allow orbital demonstrations of the 2G-1, though it was ready to do so. In the 3 decades which have passed since the HARP effort, major advances in micro chip technology and material science have greatly enhanced the potential capability of even small gun-launched systems
