As we all know, Japan doesn’t have any BRIV and BRV attack bombers, so instead of importing a Warthunder plane, let’s change N1K2-J’s armament to two 250kg bombs and change the class to attack bomber
N1K2-J setups in warthunder
N1K2-J and Meteor have similar stats,So I don’t see a problem with having an attack plane with 900 rounds of 20mm and 2x 250kg bombs
and that would take a plane out of that squadron
The N1K1-Jc 4x250kg bombs BR V ground Attacker is the version its not in war thunder sadly:
This is the N1K1-Jc its more bulky build like the P 47
The Japanese Navy had produced N1K1-Ja as its main force, but was dissatisfied with arming. The Japanese Navy has entered the production of N1K1-Jb which abolished N1K1-Ja’s Gun Pod and exchanged machine gun with newer ones. N1K1-Jb has increased the number of carrying bullets, and it became possible to install 250 kg bombs. Furthermore, it was characterized that the machine cannon was mounted 3 ° upward and the shape of the horizontal tail was changed. However, the Japanese Navy was not satisfied with this alone. In Japan at that time many bomber aircraft had become old was a problem. So the Japanese Navy attempted to install more bombs on the latest N1K1-Jb at that time. It was possible to carry a total of 1 ton bomb in this fighter called N1K1-Jc. This was an unusual amount in the fighter of the Japanese Navy at the time. A total of 30 aircraft were produced at the Himeji factory at N1K1-Jc. Two of them were remodeled to be able to carry 500 kg bombs and rocket boosters. The modified aircraft was capable of attacking aircraft carriers at a speed of nearly 740km/h due to the power of the rocket booster. By this, the attack success rate to aircraft carrier was able to be twice as high as D4Y which was the latest bomber at that time.
There is also a fighter version of Kawanishi N1K3-J that can carry 1x250 kg and six air-to-ground rockets in ventral pannier.
It’d make more sense to make the Kikka an attacker instead, since it was designed as an attack plane. Unlike the N1K2 it wouldn’t need a different version added like @Life_burns mentioned and wouldn’t need any changes since it is already well suited for that with its 800kg nuke.
its the easiest solution since all good ground attackers are not in war thunder however they can take from world of warplanes:
This one can be a BR V ground attacker:
