Support Equipment (SE) Division The SE division supplies aircraft support equipment to all organizational-level activities on the naval air station. This division performs major repair and periodic inspection and maintenance of all aviation support equipment. NOTE:  Aviation support equipment includes, but is not limited to, such items as test stands, workstands, mobile electric power plants, pneumatic and hydraulic servicing equipment, and avionics test equipment.

NAVAL AIR FACILITIES AND NAVAL AVIATION DEPOTS LEARNING OBJECTIVE: Identify the functions of naval air facilities and naval aviation depots. A  naval air facility  (NAF) performs maintenance functions on aircraft and support equipment assigned to that command. These functions sometimes include organizational- and intermediate-level maintenance. Naval air facilities are normally smaller than a naval air station. Naval air facilities are  not  equipped to handle large numbers of aircraft. A  naval aviation depot  (NADEP) maintains and operates facilities for a complete range of depot-level rework operations to include designated weapons systems,  accessories,  and  equipment.  The  depot manufactures parts and assemblies as required. It also provides engineering services in the development of changes to hardware design. The depot furnishes technical and other professional services on aircraft maintenance and logistic problems. They also perform other levels of aircraft maintenance for eligible activities when requested. The facility performs other functions as the Commander, Naval Air Systems Command may direct. Q2-10. In what respect does a naval air facility (NAF) differ from a naval air station? SQUADRONS LEARNING OBJECTIVE:  Identify the four basic types of squadrons, to include the organization within the squadron and the squadron mission; and recognize the responsibilities of squadron personnel and identify the function of squadron departments. Squadrons are designated by the purpose they serve. You should be familiar with the various types, classes, and missions of each type of squadron. TYPES OF SQUADRONS There are four basic types of squadrons—carrier, patrol, composite, and noncombatant. In this section, you will learn about squadron missions and the primary aircraft that operates within a specific squadron. Carrier Squadrons There are five types of carrier squadrons. They are fighter, attack, strike/fighter, antisubmarine, and airborne early-warning squadrons. Fighter squadrons (VFs)  are used against aircraft and ground installations to defend surface units. They escort attack aircraft, and give close air support to landing forces. These squadrons combine maximum firepower and speed. The F-14  Tomcat  is the primary aircraft assigned to a fighter squadron. Attack squadrons (VAs) are employed for various missions including enemy attack, search, bombing, mining, and torpedo warfare. Aircraft assigned to an attack squadron may be the multipurpose F-18 Hornet. Strike fighter squadrons (VFAs)   are employed for both fighter and attack missions. The F/A-18 Hornet aircraft are assigned to strike fighter squadrons. Antisubmarine squadrons (VS, HS, and HSL) include both fixed-wing aircraft (VS) and helicopters (HS and HSL). Their primary mission includes 2-7
