Operation Snapper This was an ambitious series to evaluate new weapon design principles and gather fundamental weapon design data. Among the new features tested included deuterium gas fusion boosting, external initiation, and the use of beryllium neutron reflector/tampers. Tests of new smaller implosion systems, and new schemes for achieving high core compression were also conducted. Other experiments calibrated the TOM internal neutron initiator, provided initiation time vs yield calibration data, and explored the curious "rope trick" effect seen with cable moored test devices. Test: Dog Time: 16:30 1 May 1952 (GMT) 08:30 1 May 1952 (local) Location: Nevada Test Site (NTS), Area 7 Test Height and Type: 1040 Foot Airdrop from B-45 Yield: 19 kt Dog was a test of a modified TX-7 weapon (previously tested in Buster Easy). The device tested the usefulness of deuterium gas fusion boosting (not deuterium-tritium boosting!). The predicted yield was 15-20 kt.
