Booster-stage thrust

Booster Rocket. Any high-thrust unit or assembly that fires at take-off to get a missile(such as a rocket,bomb,shell) or an unmanned or manned aircraft, to which it is attached, started along its trajectory. Usually, a booster rocket produces a much greater thrust than the 2nd stage or sustained power plant of a rocket. Booster rockets are usually propelled by a solid propellant(such as in the Nike -Ajax missile) but liq proplnts are also used. The booster rocket should not be confused with ATO, JATO or RATO engines although there is a considerable similarity in design. A liquid-propelled booster rocket is used when the requirements are more extensive than normally available from solid-pro-... 

Delta Rocket. A launch vehicle or booster or booster system consisting of one to three stages. Depending upon the thrust desired, the fuel may be LOX (liquid oxygen explosives or oxyliquits)...
