Martin B-10 139-WH2 Dutch variant early

The Martin B-10 139-WH2 (and related WH variants) were early used by the Royal Netherlands East Indies Army Air Force (ML-KNIL) for the defense of the Dutch East Indies, with 26 improved WH-2s ordered in March 1937. These aircraft were primarily deployed at airfields like Andir (Bandung) for maritime patrol and defense against Japanese forces in 1941–1942.
