U.S. Navy P-3C Orion patrol aircraft were used in the 2001 War in Afghanistan as surveillance and reconnaissance platforms. A Naval Intelligence Professionals chronology, drawing on Naval History and Heritage Command material, states that U.S. Navy P-3C Orion aircraft began surveillance and reconnaissance over southern Afghanistan on October 4, 2001, after earlier P-3C and EP-3E missions had been limited to flights along the Afghanistan-Pakistan border.
AFCENT reporting from June 2009 documents deployed U.S. Navy P-3C aircraft supporting Operation Enduring Freedom and says the aircraft provided overwatch of U.S. and coalition forces while gathering intelligence for forces on the ground and at sea.

Timeline
The first sourced milestone is October 4, 2001, when P-3C aircraft began flying surveillance and reconnaissance over southern Afghanistan before the October 7 start of U.S.-led strikes. The same chronology later describes a Navy P-3C supporting the recovery mission after a helicopter incident in October 2001 and providing video imagery and grid coordinates during a Taliban probe against Forward Operating Base Rhino.
By 2009, the P-3C mission had become a recurring CENTCOM ISR and overwatch role. AFCENT quoted the VP-8 commanding officer describing overland support to Operation Iraqi Freedom and maritime security operations, and the accompanying captions tied P-3C overwatch to both Operation Iraqi Freedom and Operation Enduring Freedom. DVIDS imagery from January 2014 also identifies VP-8 personnel with a P-3C Orion while deployed in the U.S. Fifth Fleet area supporting Operation Enduring Freedom.

Narrative
In Afghanistan, the P-3C's documented role was primarily intelligence, surveillance, reconnaissance, and overwatch rather than a named strike role. AFCENT noted that the aircraft could carry ordnance but was primarily used in the theater for ISR, using electro-optical, infrared, radar, and satellite-communications systems to detect activity and relay information to task-force commanders.
The early campaign record shows the aircraft contributing to overland reconnaissance in southern Afghanistan and to tactical support for Marines near Forward Operating Base Rhino. The December 2001 Rhino incident links P-3C video imagery and grid-coordinate reporting to a ground response, illustrating how a maritime-patrol aircraft was used as an overland sensor and targeting-support platform in the Afghan theater.
The record supports U.S. and coalition use of P-3C aircraft for surveillance and reconnaissance in the 2001 War in Afghanistan. It does not, in the sources used here, document a P-3C weapons release in Afghanistan, so the conflict-use treatment is limited to fielding, overwatch, ISR, and support to ground and maritime commanders.
