Kaisen Game: Navy Blue 90 is the Japan-only sequel to Battleship (GB).
The game's story is that you are brought in the command room of the Navy's Secret Intelligence Service again, who are addressing a national order. In the room, you see who appears to be the commander-in-chief, who has his back turned toward you. He says, "Currently, our country has been attacked by an unidentified enemy, and now we are in danger of the existence of the nation. That's where you come in again! I'm looking forward to it, kid." He then leaves quickly without even listening to your thoughts on the matter. You reluctantly decide to accept the mission and challenge the great naval battle again.
The game plays identical to its predecessor Battleship, but the main difference is the gameplay mechanics. In Navy Blue 90, you not only can select your fleet, but also purchase weapons. However, the game is noted for its brutal difficulty, as the AI seems to know exactly where your ships are and can destroy you fleet in a few turns if you're not careful.
The game spawned another Japan-only sequel, Navy Blue 98 (GB).

Music
Navy Blue 90 consists of eight songs, one more than its predecessor. That's because Navy Blue 90 now has cutscenes before each level. However, what is there is good, and most of the song has military-sounding music, complete with snare rolls. The Stage Start track is borrowed from its predecessor though.
The game's soundtrack was later arranged on the Famicom in Navy Blue (FC), most likely by Masahiro Kusunoki.
The music was recorded in the VisualBoy Advance emulator because the GBS rip plays the songs too fast. The exception is the Stage Theme music, which was recorded in NEZPlay, as it's the only song in the GBS file to play at its proper tempo, and a sound effect intrudes the Stage Theme in-game.

(Source: Music comparison; Game lacks credits.)
Neither the game nor the manual have credits, similar to the preceding title. However, both Battleship and Navy Blue 90 have soundtracks that strongly suggest that the music was written by the same sound team responsible for Thunderbirds (NES). For instance, in Battleship, the Setup music sounds identical to the Map music in Thunderbirds, and in this game, the Stage Theme music sounds identical to the various stage themes found in Thunderbirds. The game also uses Junichi Saito's sound driver.
Unfortunately, Hitoshi Saito and Masaki Iwamoto cannot remember their works because of the passing years, and the whereabouts of Junichi Saito are currently unknown.
