Direct proof of use
The Hermes 450 is directly documented in the 2001 War in Afghanistan through UK Ministry of Defence material on British Army H450 operations. In December 2010, the MOD reported that British Army Hermes 450 air vehicles had passed 30,000 operational hours supporting UK forces in Afghanistan and identified the aircraft as operated by 32 Regiment Royal Artillery.
The same MOD account described H450 tasking in Afghanistan as reconnaissance before deployments into an area, long-term pattern-of-life study, target acquisition and development, and persistent full-motion video for Task Force Helmand. A later MOD statistical bulletin covering Operation Herrick lists Hermes 450 among British Army unmanned aircraft systems used in Afghanistan and records 85,441 Hermes flying hours from May 2007 through the end of combat operations in 2014.

Timeline
Hermes was introduced to Operation Herrick in May 2007, according to the MOD's post-campaign aircraft statistics. The annual flying-hours table then records Hermes 450 use each year from 2007 through 2014, with the highest annual total in 2011.
By December 2010, the MOD said the H450 fleet had reached 30,000 operational hours and was providing most of the full-motion video available to Task Force Helmand. By the end of combat operations in 2014, the MOD recorded 85,441 total Hermes 450 flying hours in Afghanistan.

Role in Afghanistan
In Afghanistan, the documented British H450 role was intelligence, surveillance, target acquisition, and reconnaissance rather than strike. The MOD said the system used electro-optical and infrared sensors to provide brigade headquarters with persistent ISTAR out to 150 km, and that it was flown and maintained in Afghanistan to support close liaison between flight crews and Task Force Helmand users.
The Operation Herrick statistics separate the Army's Hermes aircraft from armed RAF Reaper operations. The bulletin says all British Army unmanned aircraft systems in the release were unarmed and that Army UAS did not release munitions. The supported conflict-use claim is therefore British fielding and operational use of the Hermes 450/H450 for surveillance and target-acquisition support in Afghanistan, not armed Hermes 450 strikes.
