Adm. Jonathan Greenert, chief of naval operations, has informed flag officers and senior executives in a memo that the Navy would have to halt nearly all non-deployed operations if sequestration kicks in on March 1.

According to Navy Times, the Navy would have to cancel training exercises for carrier strike groups and amphibious ready groups, a move that Greenert said in the memo would create a gap in preparing groups for deployment.

Squadrons would need about nine months of maintenance and training prior to deployment, Greenert said.

Christopher Cavas reports Greenert told officers and executives the Navy would have to cancel 30 overhauls on surface ships and cancel depot-level maintenance on about 250 aircraft, scheduled between April and September.

The Navy would also have to cut nearly 10 percent of the government’s shipyard workforce through a civilian hiring freeze and layoffs of temporary employees, the memo said, according to Navy Times.
