Submarine 707R

Plot

In the near future, the world is at war: the USR (the Undersea Silence Revolution or the Underwater Silence Revolution) a mysterious organization led by Admiral Red and his powerful submarine UX, wants to stop human exploitation of the seas, having torpedoed many ships and ports. The world's navies unite and form the Peace Keeping Navy, or PKN, to fight the "terrorists". Every major UN member contributed a submarine, though the Japanese entry is an old clunker, the 707, and it is running late to the inaugural meeting. When the meeting finally begins, Admiral Red and the UX come to spoil the show with a spread of torpedoes. Arriving late in the battle, Captain Youhei Hayami steers the 707 into the way of a torpedo launched at the supercarrier that serves as the PKN's flagship. His ship is destroyed, but the flagship survives.

Six months later, Captain Hayami is given command of the salvaged and rebuilt 707, and takes a crew of old comrades and brand new cadets to sea to fight Admiral Red once more.

Mistakes

None of the PKN submarines look particularly hydrodynamic. The most "sound" design happens to be Admiral Red's UX, as it has a hull that resembles a modern-day attack submarine. The namesake of the show, 707, looks half-way between a World War II U-boat and a nuclear attack boat.

Vertical anti-ship cluster rockets used in the intro by the UX against the two destroyers would be an inefficient weapon to aim and deploy. A torpedo would have been the more conventional option. Also, destroyers hunting subs would have helicopters out and primarily be hunting with torpedoes, not depth charges, particularly against modern submarines.

Release

The first original attempt for an anime series based on the manga was planned back in 1964 but around the same time released as an audio drama on sonosheet (ソノシート, sonoshīto, a very thin-sized record).

In 1997, an OVA was released that titled Deep-sea Fleet Submarine 707 (深海の艦隊 サブマリン707, Sinkai no Kantai Sabumarin Nana Maru Nana) by Toei Doga. The "Submarine 707R" OVAs were released by Aniplex back in Sept. 26, 2003 (mission 01) and April 24, 2004 (mission 02).
