3 may also be manually lifted up into the slot 2 by application of vertical force to pull 5 as illustrated in fig3 a rocket 22 with cylindrical tail fin 21 is illustrated in fig5 the rocket 22 is stored and shot from launch tubes 23 as shown in fig5 and 6 the launch tubes 23 are mounted in a tracked carrier vehicle 24 backblast 25 is present near the launch tubes 23 after a rocket is shot detent assembly 26 is installed on the rear of launch tube 23 as depicted in fig7 and 7a for operation the detent assembly 26 is typically attached to the rear end of a rocket launch tube 23 by means of a mounting screw passing through hole 15 as depicted in fig1 and 7a this positions the tooth 3 just beyond the rear edge of the tube 23 and permits the tooth 3 to project inward toward the center line of the tube the detent assemblies 26 are typically installed in an equally spaced pattern on the outer surface of the launch tube 23 the launch tube 23 is ready for insertion of the rocket 22 with the tooth 3 positioned at rest as shown in fig1 typically the extreme outer diameter of the rocket 22 is only slightly less than the inner diameter of the launch tube 23 when a cylindrical rocket 22 is to be loaded into the tube 23 the rocket is positioned along the center line of the tube and then inserted into the.
