EVERETT — A persistent, low-pitched horn that sounded on the waterfront Tuesday came from a U.S. Naval ship conducting tests, a Naval Station Everett spokeswoman said.
The USNS Montford Point left Everett on Wednesday morning, but is expected back in the evening, public affairs spokeswoman Kristin Ching said.
The new Military Sealift Command ship is in Everett temporarily as its crew conducts tests before its scheduled departure in the fall.
The Montford Point arrived in Everett in July after leaving San Diego. It’s the Navy’s first in a new class of mobile landing platforms — a sort of mobile pier out in the ocean. It’s more than two-and-a-half football fields long, but not quite as long as the aircraft carrier USS Nimitz.
The ship is named in honor of the black Marine Corps recruits who trained at Montford Point Camp, N.C., from 1942 to 1949.
