Description

The B7A2 (Homare 23) Ryusei was a prototype to test the new Homare 23 engine on the B7A2 which boasted 200 hp more than the Homare 12 installed on the production line of the B7A2. Other than the engine, the fuselage, wings, and armament haven't changed resulting in an enhanced B7A2 which wasn't able to be mass-produced.

The Ryusei (Homare 23) was introduced in Update "La Royale" as a reward for Battle Pass: Season XII, "Armour Breaking Ambusher". Like its previous production model, the B7A2, it's deceivingly manoeuvrable and has an even stronger engine for the same plane, still lacking any real armour. It can bite back with its defensive 13 mm machine gun or engage frontally with two wing-mounted Type 99 Model 2 cannons. While technically classified as a carrier-borne torpedo bomber, it is very capable of fulfilling the roles of dive-, level-, and torpedo bombing targets. While the max tonnage of bombs doesn't increase over the previous B6N Tenzan, it can carry four additional wing-mounted 60 kg bombs next to its bomb bay that can load two 250 kg or six 60 kg. The main playstyle of the B7A2 is more like an unarmoured attacker, using its arsenal of bombs and cannons on targets either in the sky, on the ground, or on the sea with the deadly precision of its gyrostabilized dive-bomber sight.

The B7A2 has a single 13mm steel plate behind the engine that protects the pilot from headon attacks. It works well, however the aircraft itself is still very fragile. Although it contains self sealing fuel tanks, the B7A2 is still vulnerable to catching fire. The tanks in the wing only make the problem worse. The B7A2 should not be involved in combat where it requires the use of the tail gunner. The best strategy is to use evasive maneuvers because of the plane's good maneuverability but poor survivability.

Usage in battles

The Ryusei is best utilized as a multi-role aircraft, similar to the role the Ju 87 D-5 plays. Once its payload is dropped, the B7A2 becomes a low altitude dogfighter similar to an A6M. In realistic battles, the B7A2 is often paired with aircraft such as the A6M3, A6M3 mod. 22, and A6M3 mod. 22Ko. If unable to shake an enemy off your tail, these "Zeroes" can be relied on as they have impressive low altitude capabilities.

Payload choice is dependent on target choice. If the target is a light pillbox, for instance, one does not need an 800 kg bomb. Instead, equip either of the other bomb loadout options. The same goes for most ground units, apart from arcade mini bases. The Ryusei is similar to aircraft such as the Ki-49-IIa in that it can "hover" above an enemy base or airfield, rapidly dropping its payload and diving up to altitude again. Since the B7A2 is a dive bomber, it does not have to be level to drop its payload accurately. The Ryusei's ability to "hover" above enemy mini bases and airfields can be a great help to any arcade battles team. Upgrading the crew reload speed makes this aircraft a potential game-winner, especially when in a squad.

Having a B7A2 on any team, no matter the game mode, never hurts.

History

Describe the history of the creation and combat usage of the aircraft in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
