On 5 December 1945, the 519's operational command was transferred
from the Amphibious Force to the Service Force. In mid-February, 1946,
LST 519 operated out of POE Searsport, ME, on the Penobscot Bay, to
dispose of obsolete bombs, ammunition and other ordnance.

A Liberty ship transloaded over 350 tons of aerial bombs
into a newly constructed temporary wooden bin on the main
deck. These were mostly one-thousand pound bombs, but there
were many five-hundred pounders in this first load.

It was necessary to go out beyond the continental shelf--
about one hundred fifty miles offshore--to find the necessary
minimum depth of 1,000 fathoms required for safe dumping. These
bombs were dumped along with 5,280 bazooka anti-tank rounds.

At least four such bomb-dumping missions were made before
the LST 519 was relieved by three other LSTs in mid-March.
