The Commander in Chief, U.S. Fleet established a project for airborne test, by Commander Fleet Air, West Coast, of high velocity, "forward shooting" rockets. These rockets, which had nearly double the velocity of those tested earlier at Dahlgren, had been developed by a rocket section, led by Dr. C. C. Lauritsen, at the California Institute of Technology under National defence Research Committee auspices and with Navy support. This test project, which was established in part on the basis of reports of effectiveness in service of a similar British rocket, completed its first airborne firing from a TBF of a British rocket on 14 July and of the CalTech round on 20 August. The results of these tests were so favorable that operational squadrons in both the Atlantic and Pacific Fleets were equipped with forward firing rockets before the end of the year. (Gene Hanson)
