Who would have ever thought that was a possibility??

The Japanese navy, in the summer of 1936, issued a specification call (II-Shi) for a carrier-based airplane with dive-bombing capabilities. The specifications called for a monoplane design. As usual, the leading manufacturers submitted designs. Mitsubishi, Nakajima, and Aichi received contracts to build prototypes.
After tests were completed, the Aichi company was ready to compete for the contract. One unusual characteristic of the Val was its fixed and spatted undercarriage -- the fixed landing gear added weight and decreased performance, but actually added stability to this particular design.
A second prototype was constructed with the enlargement of the wings, tail and stabilizers. An increased powerplant capacity was fulfilled by the addition of a Mitsubishi Kinsei No. 3, a 14-cylinder air-cooled radial engine. As with the first prototype, the aircraft carried two seats, one for the pilot and one for the rear gunner/radio operator.
It was later found that, because the aircraft was so maneuverable, the Val could be used as a fighter plane despite the light armament of two 7.7mm Type 97 machine guns (mounted on the engine cowling) and one flexible 7.7mm Type 92 rear-mounted machine gun.
The Val carried a 250kg (551-pound) bomb under the fuselage that was released via a swing arm. In addition, two 60kg (132- pound) bombs could be carried on racks under each wing.
Carrier qualification trials were held aboard the AKAGI and KAGA in 1940 with satisfactory results. Vals saw limited action in China in the year preceding the attack on Pearl Harbor.
Historians for the most part agree that the first bombs to fall at Pearl Harbor came from Lt. Commander Kakiuchi Takahashi's attack group of dive bombers that struck the PBY ramp at Ford Island. For the AICHI Vals, the day proved successful but costly -- a majority of the 29 aircraft lost were Vals.
Like the NAKAJIMA Kate, the Val enjoyed early success in the war but by 1944 it was suffering heavy losses and was outperformed by allied aircraft. As the war drew to a close, the AICHI D3A1 Val was pressed into Kamikaze units.
Additional comments:
When the Japanese launched their surprise attack on December 7, 1941 against Pearl Harbor, the Aichi D3A1 became the first Japanese aircraft to drop bombs on American targets.
This aircraft sank more allied ships and more shear tonnage than any other Axis aircraft in WWII.

The Baka Bomb was carried under a twin engine land-based Navy bomber. The pilot was locked in the cockpit and as the mother plane approached a target the Baka left the parent airplane to make a diving attack propelled by rocket power. The 289 mph maximum gliding speed reached 405 mph when rocket-propelled. The rocket power lasted 30 seconds.
Arrivals and departures of higher ranking officers were often noted on the Baka Bomb in front of Division Headquarters. If the officer was arriving the message would be "Welcome" painted on the nose of the bomb and the name of the person would be displayed on the side of the bomb, just under the cockpit. If departing "Sayonara" was painted on the nose. In this picture the arrival of Colonel and Mrs. J.B. Day, USA Retired, is noted. Click
Thanks for profileing the Val today Johnny. She had an impressive record of service
It is sort of strange knowing he was there at that moment. That same picture is in a book of the Maryland that my mother has. He got it while he was still in the navy. It laid around the house for years, I used to pick it up and leaf through it now and then and now to see that same picture on the internet is a little strange. My dad would have been interested to see it but he passed away about 25 years ago. It really bothered him when the Maryland was scrapped in 1959.
