Full WW2 control tower details and photos for this wartime airfield are coming soon. Please check back later as this is work progress. If you would like to contribute information or photos please get in touch.
RAF Coleby Grange sat on the Lincolnshire heathland south of Lincoln, a landscape chosen for space rather than comfort. Built in late 1938 and opened early in 1939, it began as a relief landing ground for RAF Cranwell’s training traffic, with grass runways, open hardstandings and largely hut-based accommodation. The nearby Coleby Hall was requisitioned during the war and used for officers’ mess functions, a typical example of how local estates were pulled into the air war’s infrastructure.
War changed its purpose quickly. In 1940 the airfield became a working fighter station, hosting Hawker Hurricanes of No. 253 Squadron and Boulton Paul Defiants of No. 264 Squadron as the RAF improvised air defence. The Defiant’s turret-fighter concept proved disappointing in daylight combat but found a more useful niche in night fighting, and Coleby Grange’s story soon followed the wider RAF shift toward night interception as German operations moved increasingly into darkness.
In May 1941 Coleby Grange transferred to Fighter Command’s No. 12 Group and became a satellite of nearby RAF Digby. From this point the station became strongly associated with Commonwealth night-fighter operations and the defensive belt protecting bomber bases and industrial targets across the Midlands and eastern England. No. 402 Squadron RCAF used the airfield as part of the Digby satellite system before moving on, but the most enduring association was with No. 409 (Nighthawk) Squadron RCAF, a Canadian unit formed for night defence that was based at Coleby from mid-1941 into early 1943, and returned again later in the war. The squadron’s equipment and tactics evolved with the threat: early night work relied on aircraft such as the Defiant before the arrival of the Bristol Beaufighter, whose speed, range and heavy armament made it a major step forward for night interception and ‘intruder’ operations.
Other night-fighter forces also used the station at different points, including further RCAF elements and a Polish night-fighter squadron, underlining how airfields in this part of Lincolnshire formed a flexible pool of runways and dispersals for units responding to rapidly changing operational demand. The daily rhythm at Coleby Grange would have felt permanently taut: readiness, night take-offs and recoveries, radar-directed interceptions coordinated across the wider air defence system, and constant engineering work to keep aircraft serviceable despite the punishment of night flying.
For local people, the station meant blackout restrictions and the constant throb of twin engines after dusk, with convoys of lorries carrying fuel and equipment across narrow heathland roads. For aircrew, it was a base defined by teamwork: ground controllers and radar plots fed information into the night-fighter system, while pilots and operators learned to trust instruments and each other in the dark.
After 1945 the airfield’s flying role ended, but the site’s military importance did not. It later gained a Cold War missile role, and today only fragments – sections of perimeter track and the surviving control tower/watch office – hint at the wartime station that helped guard Britain’s night skies and sustain the wider air campaign through its satellite role.
