USS Carr: Will fire guns to mark anniversary of WWII battle of Midway as it enters harbor on Friday morning.Be sure to pack earplugs on your Friday morning commute, as the US Navy is bringing out the big guns to celebrate Dorchester’s nautical roots.

The USS Carr, a 450-foot-long, 4,100-ton guided missile frigate will pull alongside Castle Island on Friday morning and fire it’s guns to commemorate the 69th anniversary of the Battle of Midway, alongside the USS Constitution. The Carr will dock at Massport Black Falcon Cruise Ship Terminal in South Boston for the weekend and members of its crew and command staff will march in Sunday’s big Dorchester Day Parade, which starts in Lower Mills at 1 p.m.

Although new Navy security regulations will prevent residents from going aboard the Carr during her stay, expect to see plenty of white uniforms ashore. A contingent of the Carr’s 200-plus crew members will also visit the New England Center for Homeless Veterans on Friday as part of a community relations project.

The Carr was launched in 1983 and was put into full service two years later as an anti-submarine escort for military supply convoys and merchant ships, using high tech sonar equipment to spot and destroy seaborne threats.

The ship is named in honor of Gunner’s mate 3rd Class Paul H. Carr of Webber Falls, Oklahoma. Carr posthumously received a Silver Star following the battle of Leyte Gulf on October 25, 1944.

During the battle, Carr commanded the rear cannon of the USS Samuel B. Roberts, a destroyer meant to protect a group of six aircraft carriers providing air support for American ground forces fighting on the beaches of Leyte Gulf.

After being confronted by an overwhelming force of Japanese battleships and cruisers, the Roberts and several other small ships rushed directly into the center of the Japanese formation, disrupting the attack and sending the attack into disarray.

Despite being heavily outgunned, the Roberts engaged a heavy cruiser for more than two hours, while Carr’s crew managed to fire more than 300 rounds from their five-inch gun.

After enemy fire crippled the gun’s cooling systems, Carr continued to load the gun by hand until one of the last shells overheated and exploded, killing most of the gun’s crew. Carr succumbed to his injuries shortly afterward while attempting to load a final shell into the gun.

This year’s arrival of the USS Carr is big news for organizers of the Dorchester Day Parade. Each year, the Navy is invited to send a ship to Boston for Dorchester’s celebration— but no ship has visited since 2008, when the USS Porter, a Navy destroyer made a port of call for the parade.
