History (Same as the 3MT5A)

Spoiler

In February 1929, the Navy issued to Mitsubishi a design requirement for a new, large, carrier attack bomber capable of carrying one torpedo or one ton of bombs. Departing from conventional designs, this was to be a twin-engined carrier-based aeroplane, powered by two 400-500hp engines. By January 1930, the official Navy specifications were concluded, and Mitsubishi accepted the order. The design of the new twin-engined bomber became the responsibility of Mitsubishi engineers Hajime Matsuhara, Naoichi Yui, and Akira Miyahara, under the supervision of G.E. Petty, who was overseeing the manufacture of the earlier Mitsubishi Type 89 Carrier Attack Aircraft.

This new aeroplane became the 7-Shi Twin-engine Carrier Aircraft, and ultimately the only twin-engined biplane landplane in the Japanese Navy. Its outward appearance resembled to some extent the Boulton Paul Sidestrand and Overstrand of the RAF. During the prolonged design phase, alterations were continually made in order to comply with the Navy’s changing requirements. The first of these aircraft was completed in September 1932 and test flights were begun on 19 October 1932 at Kagamigahara by test pilot Yoshitaka Kajima and others under his supervision. The first four of the prototypes were identical, but the fifth and following aircraft up to the total of eleven incorporated changes that were recommended by the Navy through test results. Some of the changes included the use of four-bladed propellers as well as the original single vertical tail being changed to twin fins and rudders.

During the test flights in March 1934, one of the prototypes developed severe vibration, resulting in the ailerons of both the upper and lower wings being torn off. Without this lateral control, the pilot was still able to bring the aeroplane back for an emergency landing. Following this close call, other shortcomings of design were voiced by the test pilots, particularly the poor controllability and vibration in the aft fuselage section; major defects that were never resolved. In addition, the aeroplanes were by now obsolete because of the long development period, and therefore were never considered suitable for their intended carrier operations. Consequently, the type was never put into full production.

After the first four prototypes, subsequent aircraft had twin fins and rudders, increased wing area, and additional interplane struts. After the bombers were considered to be unsuitable for carrier, or any tactical operations, they carried the designation Navy Type 93 Land-based Attack Aircraft, but were used almost exclusively for training air crews for large land-based bombers at the Tateyama Kokutai.

Twin-engined biplane carrier-based bomber.
Wooden and metal fuselage structure and metal frame wing with fabric covering. Rearward folding wings for stowage. Crew of three for attack missions, five for scouting missions.

Two 600-800hp Mitsubishi A4 fourteen-cylinder double-row radial air-cooled engines, driving four-bladed wooden propellers (3MT5). Twin nose-mounted flexible 7.7mm machine-guns and one dorsal flexible 7.7mm machine-gun. Bomb load: One 800kg (1,763lb) torpedo, or 1,000kg (2,204lb) bombs.

How is this plane armed? I don’t think there is any information about weapons anywhere.

3

in the history text

4

It’s a bit poorly planned that you have to read the stories to learn about the weapons, and it’s not in the specifications of the plane

5

well, i’m sorry, but atleast you read then… xD

Great idea 👍

7

Big, slow, poorly defended…it would be eaten up by reserve fighters.

Yet I predict it wil get an overwhelming Yes vote because its the way the WT community works.

No, it might be slow yes, but it has a 800kg torpedo or 1000kg bomb load.

It’s also mostly made from metal instead of the usual wood, that Japanese planes have.

Completely useless in WT

Interesting technical detail that is irrelevant to, and doesn’t stop it from being completely useless in, War Thunder

The B5N2 already has the same loads at 1.3 as the first of its line, and matches it with better performance. There are even better deals in other countries such as the British V-156 at 1.0 with a 1000lb, wing mgs and decent survivability.

Some planes are simply not suited to WT when they sit below the current 1.0/reserve floor. I just don’t see the type 93 having enough Meme potential to do a Po-2 and buck the trend (but as i said earlier people will vote yes regardless)
