It’s not true, well not if you read the RAF website…

The BAe Hawk T Mk1 is expected to remain in service until 2030 despite being replaced as the RAFs advanced fast jet pilot trainer by the new Hawk T Mk2. Like the Mk2, the Mk1 is a fully aerobatic, low-wing, transonic, two-seat training aircraft that is still used in a number of roles for the RAF. 100 Squadron, based at RAF Leeming, fly the Hawk T Mk1 in the ‘aggressor’ role, simulating enemy forces and providing essential training to the RAF front-line units. In addition to this, the Sqn carries out close air support training to British Army units, defence engagement tasks and participates in numerous overseas exercises throughout the year. The Mk1 is also in use with the Royal Air Force Aerobatic Team, the Red Arrows, based at RAF Scampton, in addition to the flight test and evaluation unit at MoD Boscombe Down.
The Hawk T1 is equipped to an operational standard and is capable of undertaking a war role. It has two underwing pylons cleared to carry AIM-9L Sidewinder air-to-air missiles or a telemetry pod for recording missions to enable post-flight debriefing.
hopefully it will be updated soon
