Template:Infobox aircraft The AAI RQ-2 Pioneer is an unmanned aerial vehicle (UAV) that served the United States Navy, Marine Corps, and Army from 1986 until its retirement in 2007. Initially trialed aboard the battleship Iowa, the Pioneer was deployed on battleships for artillery spotting, later expanding its role to reconnaissance and surveillance, particularly supporting amphibious operations.

This UAV was co-developed by AAI Corporation and Israel Aircraft Industries. Its development stemmed from the successful operational use of the Tadiran Mastiff UAV by both American and Israeli military forces.

Fundamentally, the Pioneer represents an enhanced version of the IAI Scout, modified with a more powerful engine to support increased payload capacity as requested by the US Navy. The original "Limbach" two-cylinder, two-stroke engine was replaced by a Fichtel & Sachs two-cylinder, two-stroke unit. The Limbach engine was paired with a 71 cm propeller from Propeller Engineering and Duplicating, Inc., based in San Clemente, California. The upgraded Fichtel & Sachs engine used a larger 74 cm propeller—rotating in the opposite direction—manufactured by the Sensenich Propeller Manufacturing Company located in Lancaster, Pennsylvania.

The Pioneer can be launched using rocket-assisted takeoff (from ships), catapult systems, or conventional runways. Recovery is conducted via net capture on ships or with arresting gear after missions lasting up to five hours carrying a payload of approximately 75-pound (34 kg). It operates continuously during day and night utilizing a gimbal-mounted EO/IR sensor, transmitting real-time analog video through a C-band line-of-sight data link. Since 1991, the Pioneer has been active in reconnaissance roles during conflicts such as the Persian Gulf War, Somalia (UNOSOM II), Bosnia under NATO intervention, Kosovo during the 1999 NATO bombing campaign, and the Iraq War. By 2005, the US Navy maintained two Pioneer systems (including one dedicated to training), while the Marine Corps operated two systems each equipped with five or more aircraft. Additionally, Israel and the Republic of Singapore Air Force have operated this UAV. The US Navy retired the Pioneer in 2007, replacing it with the AAI RQ-7 Shadow.

Globally, Pioneers are notably recognized for their involvement in the 1991 Gulf War when a unit launched from the battleship USS Wisconsin (BB-64) observed Iraqi forces surrendering on Failaka Island shortly after USS Missouri (BB-63) conducted attacks on their defensive positions. When offered to transfer a Pioneer UAV to the Smithsonian Institution, curators at the National Air and Space Museum specifically requested the model associated with this historic surrender event.

During the Gulf War of 1991, a UAV Platoon from Ft. Huachuca, Arizona operated Pioneers for flight surveillance and target acquisition missions originating from KKMC. Subsequently, as part of Operation Sand Hawk, this unit advanced northward where US Army combat engineers constructed a metal runway to facilitate UAV launch and recovery.

In Department of Defense nomenclature, "R" indicates reconnaissance capability; "Q" signifies an unmanned aircraft system; and "2" denotes it as the second model in a series of dedicated unmanned reconnaissance platforms.
