ICEBERG DEMOLITION EXPERIMENTS, 1960 



The 1960 iceberg' (lemolitioii ex])eriiiients were eoiulucted in three 

 pliases. The first phase consisted of (h-opping twenty, 1,000-pound, 

 high-explosive boinl)s from a UF2Ci aircraft on one iceberg. The 

 second phase was the phmting of thermite, an incencharv type ex- 

 plosive, on two icebergs and the third phase was tiie (Uisting of one 

 iceberg with carbon black. In all cases, the experiments were con- 

 ducted in order to test various means for the destruction of icebergs. 

 Although some damage to the l)ergs resulted, it must be admitted that 

 all of the means tried were unsuccessful in destroying the ice])ergs. 



The aerial bombing experiments were a direct continuation of the 

 bombing program of 1959 with the exception that high explosive 

 bombs were substituted for thei-nhte l)ond)s. The United States De- 

 partment of the Navy made available ten, 1,000-pound general-pur- 

 pose bombs and ten, 1,000-pound, semi-armor-piercing bombs for the 

 experiment. The Coast Guard assigned a UF2G (Gruman Albatross) 

 amphibian aircraft from the U.S. Coast Guard Air Station, Brooklyn, 

 N.Y., with Lieut. C. E. Mueller, USCG, as plane commander and 

 Ens. J. M. Tanguay, USCG, as copilot, from the U.S. Coast Guard 

 Air Station, Salem, Mass., to perform the bombing experiments. The 

 aircraft reported to the Commander, International Ice Patrol, on 17
