Military hangars and buildings

 

A military hangar is a closed building-like structure whose function is to hold aircrafts or spacecraft in protective storage. They are mostly made of metal, but others are made of other materials such as wood and concrete. The military hangers are meant to support defence needs in difficult environmental conditions, extreme climatic conditions as well as, very demanding terrain. Other functions include protection from direct sunlight, a site for maintenance, repair and manufacture of military aircraft. They are also useful in assembly and storage of aircraft on carriers, ships and airfields. Their sizes depend on their purpose, and the door is always large enough to allow for the passage of the aircrafts. 

Military hangars aboard ships

Warships normally carry aircraft aboard and, thus, the need for hangars for use in the aircraft storage and maintenance. They are normally situated adjacent to the flight deck, commonly seen in frigates, destroyers and cruisers or below the flight deck. Those that are found underneath have elevators to lift the aircraft; as commonly seen in aircraft carriers and assault ships. When space is limited like on smaller ships, both the deck and the hangar share the same place on the ship.

Underground hangar

Underground hangars are military hangers that are normally dug into the side of a mountain. This kind of a military hanger is specifically for protection. They are larger and more sophisticated compared to the types of hangars, and are mainly used for more classified operations. The underground hangar complex is made up of tunnels that contain the normal elements of a military airbase with such things as fuel storage, rooms for maintaining the aircraft systems, weapon storage facilities, a communications centre, kitchens, briefing rooms, dining rooms as well as sleeping rooms for the personnel. Besides, the underground hangars are equipped with electrical generators for power generation.

Steel hangars

They are the most common hangars. Steel hangars can be classified into three classes: Truss, girder, and long-span joist construction; with most modern hangars falling under the truss class. TheTruss technology for hangar building is based on bridge design for safety and durability, which makes it durable and efficient, just like most bridges.

Wood hangars for aircrafts

The Wood hangars are those whose primary structural components are made up of heavy timber construction. They are normally constructed for temporary military mobilization and were originally constructed because of a shortage of steel. Due to the modifications made to them, they may be considered permanent or semi-permanent structures in modern times. Their construction and use were primarily meant for overseas purposes. They offer protection from the sunlight and moderate climatic conditions, as well as serving as sites for repair and maintenance of aircrafts, but not for defence reasons.

Composite hangars

Composite hangars have primary structural components constructed using more than one structural material, that is, they are made of concrete, wood and steel. They are rare in military structures, but for the few that have been used, the motivation has been the cost-effective, beauty and ease of construction features. Additionally, they are not as permanent as the steel hangars but are obviously stronger than the wooden and concrete hangars.
