- Zero length launch
The zero length launch system or zero length take-off system (ZLL, ZLTO, ZEL, ZELL) was a system whereby jet fighters and
attack aircraft were intended to be placed uponrocket s attached to mobilelaunch platform s. Most zero length launch experiments took place in the 1950s, during theCold War .The primary advantage of a zero length launch system is the elimination of the need for a vulnerable
airfield for takeoffs. In the event of a sudden attack, air forces could field credible air defenses and launch airstrikes even with their own airbases destroyed. Although launching aircraft using rocket boosters proved to be relatively trouble-free, zero length launch systems still required a conventional runway if the aircraft was expected to land. Bulky mobile launching platforms also proved to be expensive to operate and difficult to transport. Security would also have been an issue with mobile launchers, especially if equipped with nuclear-armed strike fighters.The
United States Air Force ,Luftwaffe , andSoviet Air Force all conducted experiments in zero length launching. All works upon ZLL aircraft were abandoned due to logistical concerns and the increasing efficiency ofguided missile s.Manned Aircraft Involved in ZLL Testing
* Republic F-84G Thunderjet
* North AmericanF-100D Super Sabre
* LockheedF-104 Starfighter
* Mikoyan-GurevichMiG-19 "Farmer"
* North AmericanXF-108 Rapier - (aircraft program cancelled)The desire to field combat aircraft without depending on vulnerable landing strips also motivated development of aircraft capable of vertical (
VTOL ) or short (STOL ) takeoffs or landings. Examples of these include theHawker Siddeley Harrier and the McDonnel DouglasF-15S/MTD .External links
