Stratos 4

Stratos 4 (ストラトス・フォー, Sutoratosu Fō) is an anime series by Studio Fantasia and Bandai Visual, and directed by Takeshi Mori. Originally spanning a 13-episode anime TV series, which premiered across Japan between January 5, 2003 to March 30, 2003, the series was continued onto three OVA-series sequels, the first of which was released on 28 May 2004 and spanned 2-episodes, followed by Stratos 4: Advance, which spanned 6 episodes and was released on 25 March 2005, and Stratos 4: Advance Final, which was released on 22 September 2006 and spanned 2-episodes, respectively.

The series has been broadcast by the anime satellite television network, Animax, across its respective networks worldwide, including East Asia, Southeast Asia, South Asia, Latin America, and other regions. The original 13-episode television series and its first subsequent two-episode OVA series were licensed for North American distribution by Bandai's distributive unit across the region, Bandai Entertainment. But, when Bandai Entertainment shut down, the series became unlicensed.

Story

Fifty years before the series begins, scientists learn that a group of comets will enter the Solar System on a collision course with Earth. The United Nations set up a two-tiered global defense system against the threat: the primary one being a space-based Comet Blaster group and the secondary being a ground-based Meteor Sweeper group. Most of the series takes place on an airbase on Shimoji Island in 2024, where Mikaze and her friends are tasked to defend the Earth from large fragments left over after a failed attempt by the Comet Blasters, who are based on one of seven space stations, to annihilate a comet. All is going well until a large meteorite crashes into a lightly populated island leading the girls on a run to find out the truth about the comets.

Flight profile

Flight profile of the TSR-2MS

In the event a comet approaches the Earth with a high collision probability, all Meteor Sweeper (MS) bases are put on Standby. In the case where the Comet Blasters fail to shatter completely the comet, allowing one or more fragments to fall into the Earth's atmosphere, the Meteor Sweepers in the expected impact zones are dispatched to intercept those fragments.

Stratos 4 focuses on one such MS team, located on the island of Shimoji in Japan. The Shimoji MS squadron operates a fleet of TSR-2MS interceptors, each armed with one Trident anti-meteor hi-explosive missile, and equipped with an internal booster (named "Third Engine") and two booster packs (RATOs).

The aircraft take off in a rocket-like manner where it is launched at an angle from a truck-mounted railed launchpad rather than taking off conventionally by runway (except in episode 10 and OVA 5 of Advance). For redundancy reasons, always two aircraft are launched together per dispatch. The pilots fly the aircraft in a prone position. This is never explained; it is assumed to be used to counteract G-force. At mid altitude (30,000-40,000 ft), the boosters burn out and are dropped.

The TSR-2MSs rise swiftly into the stratosphere, where they fly in an inverted position like the space shuttle before delivering their payload. The "Third Engine" is ignited while inverted. At high altitude (80,000-100,000 ft), jet throttle is reduced, then, at very high altitude (120,000-150,000 ft), "Third Engine" throttle is also reduced. Both aircraft return to an upright attitude, lock onto the target and fire the Trident missile one after another (within approximately 5 seconds apart).

The TSR-2MS is depicted in episode CODE 103: Decision Height as being able to fly high enough to reach low Earth orbit before it runs out of fuel and stalls. The TSR-2MS has no braking chute, but has an arresting hook for emergency landings. The aircraft that "gets the kill" is later painted with a red comet icon on the fuselage side.

With the meteor destroyed, the base returns to Standby.
