Developed by Yokosuka Naval Air Technical Arsenal, Keiun is the latest state-of-the-art prototype high-altitude reconnaissance aircraft. The Keiun is a unique design with all sorts of new innovations and now powered by the Ne turbojet engine, this is what made the plane become a jet fighter-bomber.
- Can be acquired through Akashi's Improvement Arsenal by upgrading a Prototype Keiun (Carrier-based Reconnaissance Model) with a Ne Type Engine.
Characteristic of Jets
- Can only be used on:
- When used on Carriers, an additional Jet Assault phase will commence before every aerial combat phase. When used in Land Base Aerial Support, an additional Jet Assault phase will commence before every Land Base Aerial Support sortie.
- Unlike regular aircraft, jets consume steel in every battle whenever Jet Assault phase takes place, even if no planes are lost.
- Steel consumption cost per battle is 0.2 × no. of plane when battle start × LBAS deployment cost (rounded off to integer).
- The steel reduction takes place during the sortie, so there is no visual indication within the game to remind players that such reduction has taken place. The expense in steel can only be seen when comparing pre-sortie steel levels with post-sortie levels.
- Steel is only consumed when Jet Assault is initiated. In situations where the Jet Assault phase does not activate, such as anti-submarine-only battle, air raid battle and night battle nodes, steel will not be consumed.
- Jet-powered fighter-bombers are treated as dive bombers, therefore aircraft carriers equipped with jet bombers cannot attack Installations during the shelling phase. However, they can still target Installations during the Aerial Combat phase.
- Jet-powered fighter-bombers do not count towards triggering aircraft carrier cut-in (CVCI).
