30th Bombardment Squadron
military unit
See United States Air Force Thunderbirds for the squadron's successor unit
The 30th Bombardment Squadron is a United States Air Force unit. On 19 September 1985 it was consolidated with the USAF Air Demonstration Squadron, also known as the United States Air Force Thunderbirds. The squadron was first activated in 1917 when the United States entered World War I as the 30th Aero Squadron. It deployed to France in the fall of 1917 and served as a construction unit throughout the war, returning to the United States at the end of 1918 for demobilization. It was reconstituted as the 30th Bombardment Squadron in March 1923 and served with reserve personnel during the decade. In 1932, the squadron became a regular unit, serving at bases in California.
The squadron, which had equipped with early models of the Boeing B-17 Flying Fortress, deployed to the Philippines in the fall of 1941 to reinforce the American garrison there. The squadron's base at Clark Field was attacked on 8 December 1941. During the month of December, the squadron withdrew through the Philippines to Darwin, Australia, although it continued to stage through Philippine bases through the spring of 1942. In late 1942, the squadron was withdrawn from combat and reformed as an Operational Training Unit.

Why this record matters
“30th Bombardment Squadron” is worth following because a concise public description often conceals a longer documentary argument. Here, 30th, Bombardment and Squadron provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 22, 2026. The linked authority identifier is Q4634581. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1985, 1917, 1918 and 1923.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
