aircraft:

The McDonnell Douglas F/A-18 Hornet is an all-weather supersonic, twin-engine, carrier-capable, multirole combat aircraft, designed as both a fighter and attack aircraft (hence the F/A designation). Designed by McDonnell Douglas and Northrop, the F/A-18 was derived from the latter's YF-17 in the 1970s for use by the United States Navy and Marine Corps. The Hornet is also used by the air forces of several other nations, and formerly by the U.S. Navy's Flight Demonstration Squadron, the Blue Angels.

The F/A-18 was designed to be a highly versatile aircraft due to its avionics, cockpit displays, and excellent aerodynamic characteristics, with the ability to carry a wide variety of weapons. The aircraft can perform fighter escort, fleet air defense, suppression of enemy air defenses, air interdiction, close air support, and aerial reconnaissance. Its versatility and reliability have proven it to be a valuable carrier asset.

The Hornet entered operational service in 1983 and first saw combat action during the 1986 United States bombing of Libya and subsequently participated in the 1991 Gulf War and 2003 Iraq War. The F/A-18 Hornet served as the baseline for the Boeing F/A-18E/F Super Hornet, its larger, evolutionary redesign, which supplanted both the older Hornet and the F-14 Tomcat in the U.S. Navy.

aggressor squadrons :

An aggressor squadron or adversary squadron (in the US Navy and USMC) is a squadron that is trained to act as an opposing force in military wargames. Aggressor squadrons use enemy tactics, techniques, and procedures to give a realistic simulation of air combat (as opposed to training against one's own forces). Since it is impractical to use actual enemy aircraft and equipment, surrogate aircraft are used to emulate potential adversaries.
The first formal use of dissimilar aircraft for training was in 1969 by the United States Navy Fighter Weapons School (better known as "Topgun"), which used the A-4 Skyhawk to simulate the performance of the MiG-17. The success of formalized dissimilar air combat training (DACT) led to transition of Navy Instrument Training Squadrons equipped with the A-4 into Adversary Squadrons at each master jet base. The United States Air Force followed suit with their first aggressor squadrons at Nellis AFB equipped with the readily available T-38 Talon.
