America's first "rocket-assisted" Take-off, an Ercoupe fitted with a GALCIT booster, in 1941

JATO is an acronym for Jet-Assisted Take Off. The term is used interchangeably with the (more specific term) RATO (for Rocket-Assisted Take Off). It is a system for helping overloaded planes into the air by providing additional thrust in the form of small rockets. See also assisted take off.

Early experiments

Early experiments with using rockets to boost gliders into the air were conducted in Germany in the 1920s (Lippisch-Ente), but practical JATO systems were first[citation needed] introduced by the RAF early in World War II. These used fairly large solid fuel rockets to shoot planes (typically the Hawker Hurricane) off a small ramp fitted to the fronts of merchant ships, known in service as CAM ships, in order to provide some cover against German reconnaissance planes. After firing, the rocket was released from the back of the plane to fall into the water (and sink). The task done, the pilot would fly to friendly territory if possible or parachute from the plane, hopefully to be picked up by one of the escort vessels. Gliders or Sailplanes are heavier-than-air aircraft primarily intended for unpowered flight. ... “RAF” redirects here. ...

The Luftwaffe also used the technique in order to help their small bombers into the air with loads that would have made the takeoff run too long otherwise. This became especially important late in the war when the lengths of usable runways were severely curtailed due to the results of Allied bombing. Their system typically used Walter HWK 500 Starthilfe ("start-help") rocket engines driven by breaking down hydrogen peroxide. A parachute pack at the front of the motor was used to slow its fall after being released from the plane, so the system could be re-used. Other German experiments with JATO were aimed at assisting the launch of interceptor aircraft such as the Messerschmitt Me 262 so that they could reach enemy bomber formations sooner.

Post WWII

After World War II JATO became particularly common owing to the low slow-speed thrust of then-current jet engines or for assisting heavy aircraft; the prop-engined Avro Shackelton used Armstrong Siddeley Viper turbojets for takeoff. As the quality and power of the engines has grown, JATO has fallen from favour. It is still used, however, when heavily-laden aircraft need to take off from short runways or when operating in "high and hot" conditions. Two similar zero-length launch experiment programs were carried out by both the US Air Force in the late 1950s with a modified Republic F-84, designated the EF-84G, and by the Soviet VVS in the USSR at around the same time, with a modified MiG-19 fighter, designated SM-30, launched from a special launcher, using a nearly identical solid fueled rocket booster design to that of the EF-84G, which used the MGM-1 Matador cruise missile's solid fuel booster.

Operation Credible Sport was a United States military operation plan in late 1980 to rescue hostages held by Iran using C-130 cargo planes modified with rocket engines to enable a very short take off and landing. The plan was canceled after an accident during the test landing when JATO units designed to cushion the landing failed and caused the aircraft to crash-land.

In all of these cases the term "jet" is correct but the system is more accurately called RATO. However JATO remains the most popular version, apparently due to its US origin.




JATO Urban Legend

The JATO Rocket Car is a famous urban legend that relates the story of a car equipped with JATO units for a lark, that is later found smashed into a mountainside. This story is often given as an example of a Darwin Award; however it appears to be apocryphal, with no basis in fact. A particularly elaborate form of this legend has been promulgated by hacker group Cult of the Dead Cow in the ostensibly autobiographical story "Rocket Car". This legend was tested in 2003 on the Discovery Channel show MythBusters. They replicated the scene and the thrust of the JATO with some commercially-available amateur rocket motors. The car did go very fast, but did not quite make 300 mph, and did not become airborne, although the filming helicopter with the r/c driver Jamie Hyneman in couldnt keep up with it. However, a nearly verbatim copy of the cDc version is detailed here, involving a car frame attached to an old mine railcar and a JATO rocket as described in the Cult of the Dead Cow version. The reader must determine whether the presence of two such accounts amounts to verification or copying. The famous account of the JATO Rocket Car was one of the original Darwin Awards winners: a man who supposedly met his death in a spectacular manner after mounting a rocket engine on a common automobile. ... An urban legend or urban myth is similar to a modern folklore consisting of stories often thought to be factual by those circulating them. ... The Darwin Awards website logo A Darwin Award is a tongue-in-cheek honor named after evolutionary theorist Charles Darwin. ... CULT OF THE DEAD COW, also known as cDc, is a computer hacker and DIY media organization founded in 1984 in Lubbock, Texas. ... This article does not cite any references or sources. ...
