MILITARY aircraft may fly low over Clacks next week as exercise Typhoon Warrior 21 continues in August.

Fast jets, helicopters and transport planes are taking part in “large force exercise involving up to 60 military aircraft operating in mixed formations” - explained Civil Aviation Authority (CAA) documents.

The joint exercise will see RAF and USAF aircraft taking part along with US contractors Draken Aviation, which offers airborne adversary support - often referred to as red air.

Flying days will include August 17, 19, 24 and 26 with Clacks among the areas potentially affected.

An airspace co-ordination notice by the CAA shows the exercise will take place along and off the east coast with the Firth of Forth included.

Aircraft involved will be departing from RAF bases Lossiemouth, Waddington, Leeming, Coningsby, Odiham, Brize Norton, Mildenhall, Lakenheath, and Benson as well as Teesside International Airport.

According to the CAA, sorties on exercise could be airborne between 8.30am and 2.15pm on the aforementioned days.

When flying low, aircraft taking part could be spotted at altitudes as low as 250ft or even 100ft above ground level.

Formations in the sky will include fighter jets, such as the twin-engine multi-role RAF Typhoon FGR4 based at Lossiemouth and the USAF McDonnell Douglas F-15.

Helicopters will include the Boeing Ah-64 Apache, CH-47 Chinook and RAF Puma HC2.

CAA documents added: “Exercise traffic will conduct air-to-air combat radar profiles (100nm+), supersonic flight, radar and communications jamming, and air combat serials.”
