Marine Bombing Squadron 443 (VMB-443) was a United States Marine Corps medium bomber squadron activated during World War II. Formed in 1943, the squadron was equipped with PBJ-1, the naval version of the B-25 Mitchell bomber. VMB-443 deployed to the Pacific Theater, where it conducted bombing, strafing, and anti-shipping missions in support of Allied operations in the Solomon Islands and the Philippines. The squadron was deactivated in 1945 following the end of the war, having played a vital role in the Marine Corps' aerial campaign against Japanese forces.
