The hangar is three decks high, and it''s flanked by various single-deck compartments on both sides. There are also four giant elevators surrounding the hangar, which move the aircraft from the hangar to the flight deck. The high-speed, aluminum hydraulic elevators are big enough and powerful enough to lift two 74,000-pound (~34,000-kg) fighter jets.
Storage location. Aircraft should be ideally parked or stored on a flat surface with the nose pointing in the direction of the prevailing winds to limit the effect of wind and gusts on the aircraft. Landing gear safety devices. Landing gear safety devices must be put in place to prevent unwanted landing gear retraction.

Developed in the 1950s, steam catapults have proven exceptionally reliable. Carriers equipped with four steam catapults have been able to use at least one of them 99.5% of the time. However, there are a number of drawbacks. One group of Navy engineers wrote: "The foremost deficiency is that the catapult operates without feedback control. With no feedback, there often occurs large transients
In this work, we divide ESS technologies into five categories, including mechanical, thermal, electrochemical, electrical, and chemical. This paper gives a systematic survey of the current development of ESS, including two ESS technologies, biomass storage and gas storage, which are not considered in most reviews.
