Some of the more popular airplane wrecks dives in Truk Lagoon include the Kawanishi H8K1 “Emily” Flying Boat and the Mitsubishi G4M “Betty” Bomber. Bomber aircraft were often given female names and fighter aircraft were often nicknamed with men’s names.
The Emily Flying Boat was known for its long range and nicknamed the “Flying Porcupine” was very difficult to shoot down because it had self-sealing fuel tanks and internal fire extinguishers. It held a crew of 16, had a 37m (124ft) wingspan and was 28m (92ft) long. It had four 1850 horsepower Mitsubishi Kasei engines.
Airplane Wrecks in Truk Lagoon




This particular wreck was bringing back the Commanding Officer of the Fourth Fleet, his Chief of Staff and other senior Japanese Naval Officers from a meeting in Palau. US fighters repeatedly attack and the pilot still managed to escape the fighters and return to Truk, although while trying to land the damaged aircraft the pilot lost control and it crashed and sank. The pilot, Admiral and Chief of Staff survived.
An easy wreck to dive at 15m (50ft), much of the plane is intact including several propellers. Near the plane sit several gauge panels and other airplane parts.
The Betty bomber was a small twin engine plane that sits in 15-18m (50-60ft) in the sand. Made to be as light as possible, the fuel tanks were unprotected and easily caught fire, making them very vulnerable. This wreck crashed on trying to land on Eten Island and it is unknown if it was shot down or crashed on its own. The engines are found about 90m (300ft) in front of the rest of the wreck closer to the island. This plane would hold a crew of seven, had a wingspan of 25m (85ft), was 20m (66ft) long and would have four 12.7mm machine guns, one 20mm cannon, and one 1750lb bomb.
