RAF Grafton Underwood

Royal Air Force Grafton Underwood or more simply RAF Grafton Underwood is a former Royal Air Force station located northeast of Kettering, Northamptonshire, England.

Royal Air Force use

The airfield at Grafton Underwood was opened in 1941 and was first used by the RAF Bomber Command No. 1653 Heavy Conversion Unit RAF with Consolidated Liberators. The original runways were approximately 1,600 yards and 1,100 yards in length. However, these were unsuitable for the operation of heavy, four-engined bombers and the field was upgraded to Class A airfield standards, including the lengthening of the runways to the required 2,000 yards for the main and 1,400 yards for each of the others, started in late 1942.

United States Army Air Forces use

Grafton Underwood was assigned United States Army Air Forces Eighth Air Force in 1942. Its designation was USAAF Station 106.

* 443d Sub-Depot
* 18th Weather Squadron

15th Bombardment Squadron (Light)

The first United States Army Air Forces Eighth Air Force tenant on Grafton Underwood was the 15th Bombardment Squadron, arriving on 12 May 1942 from Batchelor, Australia. The squadron flew the British Boston III light bomber. The 15th was originally part of the 27th Bombardment Group (Light), based in the Philippine Islands, however the group's planes (A-24's), did not arrive by 7 December 1941. Due to the deteriorating situation in the Philippines after the Japanese attack, they were diverted to Australia where they reformed into a combat unit and fought in the Dutch East Indies and New Guinea Campaigns.

When the 27th Bombardment Group was inactivated and transferred back to the United States for re-equipping, the surviving members of the group were first transferred back to the United States, then to the UK.

At the time Grafton Underwood was lacking many facilities, and the squadron moved to RAF Molesworth in mid June.

97th Bombardment Group (Heavy)

The ground echelons of the 97th Bombardment Group, having sailed from the New York Port of Embarkation aboard HMS ''Queen Elizabeth'' on 4 June 1942, arrived at Gourock, Scotland on 10 June 1942. After disembarking the following day, they traveled by train and then by truck to Northamptonshire, England and soon they arrived at their respective RAF Airdromes on 12 June 1942. The 97th Bomb Group Headquarters personnel and the 340th and 341st Bomb Squadron ground personnel went to RAF Polebrook. The 342nd and 414th Bomb Squadron ground personnel went to RAF Grafton Underwood. On 6 July 1942 a 97th Bombardment Group flight echelon from two Boeing B-17E Flying Fortress Bomb Squadrons (four B-17Es each from the 342nd and the 414th), which had been held up at Goose Bay by bad weather, arrived at their assigned RAF Base in England (Grafton Underwood) and rejoined their ground echelon. The newcomers found their old comrades, after almost a month abroad, adept at calculations in shillings and pence and authorities on other peculiarities on life in England.

The first 97th Bombardment Group Flying Fortresses reached Prestwick on 6 July when 41-9017, 41-9019, 41-9023, 41-9024, 41-9026, 41-9042, 41-9103 and 41-9115 arrived. These eight Flying Fortresses from the 342nd and 414th Bomb Squadrons were the first 97th Bomb Group B-17's to arrive at their assigned RAF base, and arrived the same day (6 July 1942) at Grafton Underwood detailed as follows:

Both RAF Polebrook Peterborough and Grafton Underwood airfields were originally built as 2-squadron bases. Consequently, the 97th Bombardment Group had to operate out of two separate RAF bases until the Polebrook facility was upgraded to support a full 4-squadron bomb group. On 8 September 1942 the 342nd and 414th Bomb Squadrons relocated from Grafton Underwood to Polebrook.

The 97th Bomb Group is famous for flying the first all-American Flying Fortress bombing mission against German-occupied territory in Europe on 17 August 1942 by attacking the railway marshalling yards at Sotteville-lès-Rouen in France. The lead aircraft in the first flight group of six B-17s was ''Butcher Shop'', which was copiloted by the Group Commander Colonel Frank A. Armstrong, and piloted by the squadron commander of the 340th Captain Paul W. Tibbets (who later flew the '' Enola Gay'' to Hiroshima Japan on the first atomic bomb mission). The lead aircraft in the second flight group of six B-17s was ''B-17E Yankee Doodle 41-9023'', which was copiloted by 2nd Lt. John R. Dowswell and piloted by Captain Rudolph Emil "Rudy" Flack the squadron commander of the 414th, Grafton Underwood base commander and mission commander (http://www.americanairmuseum.com/person/246743), and who carried Brig. General Ira C. Eaker the commander of the VIII Bomber Command as an observer on board his Flying Fortress.

From 17 August 1942 through 21 October 1942 the 97th Bombardment Group flew 16 officially numbered bombing missions (plus a couple of off-book missions) and attacked airfields, marshalling yards, industries, naval installations and other targets in France, Belgium and Holland (the Low Countries). Next, the 97th Bombardment Group was transferred to the Twelfth Air Force in the Mediterranean theatre. For the most detailed accounting of the activities of the 97th Bombardment Group from the 414th Bomb Squadron first commanding officer's perspective from February 1942 through 5 March 1943, refer to the following book's Chapter 7 (Fast Track Training for Overseas Assignment 1942), Chapter 8 (Combat Missions in Europe with the Eighth Air Force 1942) and Chapter 9 (Combat Missions in North Africa with the 12th Air Force 1942-43), which is freely available to download and view the latest version of the book via this Facebook link: https://www.facebook.com/Untold-Stories-of-Colonel-Rudy-Flack-302118180261150/.

Lastly, the 97th Bombardment Group was transferred to the 15th Air Force and went on to lead a number of secret and daring missions all over Europe.
