Some 2500 Betty bombers were built by Japanese from 1938. With a wingspan of 80ft and a length of 67ft they had a range of 3125 miles, a top speed of 285mph and were armed with 7.7mm & 20mm guns at the nose, either side and from a dorsal turret. The payload consisted of up to 4000lb of bombs. While Betty was its official codename, the Flying Cigar was a more popular name. The Japanese turned Truk’s Etem Island into a vast airfield and it is off the end of the runway, in 50ft of water that can be found a good specimen of this bomber. Its engines are some 75 yards behind the body, suggesting that it crashed either on take-off or after an abortive landing. Visitors can enter the plane through the front or towards the rear and they can even open the observation hatch behind the cockpit. Guns can be found on the sand on the port side and by the starboard tail wing, and radios and other communication equipment can also be seen. Being shallow visitors can spend a long time on this wreck, but being quite small it is a quick dive.
