WASHINGTON — United States Navy ships worldwide will suspend operations for a day or two this week to examine basic seamanship and teamwork after the second collision of a Navy destroyer with a large commercial ship in two months, the Navy’s top officer said on Monday.

The officer, Adm. John Richardson, the chief of naval operations, said he had ordered two major actions after the collision between the destroyer John S. McCain and an oil tanker early Monday off the coast of Singapore that left 10 sailors missing and five others injured.

First, Admiral Richardson said, he ordered an “operational pause” for Navy fleet commanders to review teamwork, safety, seamanship and other “fundamentals” aboard all 277 Navy vessels. Commanders will space out the review to avoid hampering operations, like the war games in South Korea that started on Monday.

Second, the admiral said, he ordered a broader, monthslong review to examine the specific problems with the Navy’s Seventh Fleet, based in Japan, as the Navy has suffered four major ship accidents in the western Pacific since February.
