Abstract

The paragraph should give a three to five sentence abstract about your entire London HUA experience including 1) a summary of the aims of your project, 2) your prior experience with humanities and arts courses and disciplines, and 3) your major takeaways from the experience. This can and should be very similar to the paragraph you use to summarize this milestone on your Profile Page. It should contain your main Objective, so be sure to clearly state a one-sentence statement that summarizes your main objective for this milestone such as "a comparison of the text of Medieval English choral music to that of the Baroque" or it may be a question such as "to what extent did religion influence Christopher Wren's sense of design?"

Introduction


I suggest you save this section for last. Describe the essence of this project. Cover what the project is and who cares in the first two sentences. Then cover what others have done like it, how your project is different. Discuss the extent to which your strategy for completing this project was new to you, or an extension of previous HUA experiences.

As you continue to think about your project milestones, reread the "Goals" narrative on defining project milestones from the HU2900 syllabus. Remember: the idea is to have equip your milestone with a really solid background and then some sort of "thing that you do". You'll need to add in some narrative to describe why you did the "thing that you did", which you'd probably want to do anyway. You can make it easy for your advisors to give you a high grade by ensuring that your project milestone work reflects careful, considerate, and comprehensive thought and effort in terms of your background review, and insightful, cumulative, and methodical approaches toward the creative components of your project milestone deliverables.

Section 1: Background

Aircraft Production Ramp up

After the breakup of the League of Nation' Disarmament Conference in 1934, Britain began its expansion of its Air Force. At first, the expansion was nothing more than than an attempt to impress the Germans with 'Scheme A'. Shortly after this though, Britain's Secretary of State for air, Sir Philip Cunliffe-Lister increased the expansion program. The goal for the program was to increase the RAF by 588 aircraft to include a total of 1512 aircraft. To make the goal a reality, the Shadow Factory scheme was put into place in March 1936. This program built state owned plants that were managed by non-aerospace industrial manufacturers who built products designed by aircraft makers. One example, Lord Huffield's company, Wolseley, was given control of the Castle Bromwich factory that built Spitfires under the guidance of Vickers Supermarine. In the end, Huffield's company was very inefficient at running the factory which was then turned over to Vickers Supermarine directly to manufacture Spitfires. This was an instance of the Shadow factory scheme not working well and hurt Britain at the beginning of the Battle of Britain because of the limited number of Spitfires that were available. Other manufacturers also had issues, but some excelled at their job, it was a mixed bag of performance.[2]

British RAF

Blenheim

Blenheim[3]

The Bristol Blenheim was a two seater night fighter that was converted from the original design of a light bomber. Powering the plane were two 840 hp Bristol Mercury VIII radial piston engines. It had a maximum speed of 260 mph at 12,000 ft, with a service ceiling of 24,600 ft. It had a range of 1,460 miles on its internal tanks. The empty weight of the plane was 8,100 lbs with a maximum takeoff weight of 12,500 lbs. it had a wingspan of 56 ft 4 in, a length of 39 ft 9 in, and a height of 12 ft 10 in. It was armed with six 0.303 in machine guns.[4]

Defiant

Defiant[5]

The Boulton Paul Defiant was a two seater fighter. It was powered by a 1,030 hp Tolls-Royce Merlin III twelve cylinder liquid cooled engine. It had a maximum speed of 304 mph at 17,000 ft with a service ceiling of 30,348 ft. It had a maximum range of 465 miles. Its empty weight was 6,281 lbs with a maximum takeoff weight of 8,424 lbs. It had a wingspan of 39 ft 4 in, a length of 35 ft 4 in, and a height of 11 ft 4 in. It was armed with four 0.303 in Browning machine guns mounted to a hydraulically operated turret behind the pilot. The turret allowed for exceptional coverage but being a heavier aircraft it was sluggish in combat and was vulnerable to conventional enemy fighters. After several massacres at the hands of the Luftwaffe the fighter transitioned into a Night Fighter but when that didn't go well either the fighter was phased out.[6][7][8]

The Hawker Hurricane was a single seater fighter/fighter-bomber. It was powered by one 1,280 hp Rolls-Royce Merlin XX V-12 piston engine. It had a maximum speed of 342 mph at 22,000 ft with a service ceiling of 36,500 ft. The range of the plane was 480 miles with internal tanks, but also had external tanks with a capacity of 90 gallons which about doubled this range. The empty aircraft weighed in at 5,500 lbs, with a maximum take-off weight of 7,300 lbs. The plane had a wingspan of 40 ft, length of 32 ft 2 1/2 in, and a height of 13 ft 1 in. It was armed with twelve 0.303-in forward-firing machine-guns, plus two 250 lb or one 500 lb bombs. The later versions of this aircraft replaced the twelve 0.303-in machine guns with four 20 mm cannons.[10]

Empty it weighed in at 4,796 lbs with a maximum takeoff weight of 5,332 lbs. It had a wingspan of 36 ft 10 in, a length of 29 ft 11 in, and a height of 11 ft 5 in. It was initially armed with 8 0.303-in Browning machine guns, but later on in the war 20 mm Hispano cannons were introduced. There were several different wing designs throughout its lifetime that were used to house different weapons. The original A wing housed eight 0.303-in machine guns, the B wing housed four 0.303-in machine guns and two 20 mm cannons, and the C wing was interchangeable and could be formatted like the previous A and B wings or a third option of four 20 mm cannons.[11] Later in the war more wing variants were developed, the D wing was a specialized wing for photo reconnaissance aircraft providing extra fuel to allow for a range of up to 2000 miles, the E wing housed two 20 mm and two 0.5 in cannons as well as the capacity to hold a 250 lb bomb on each wing.[12][13]

British Fighter Command

The Fighter Command's Commander-in-Chief during the lead up to and during the Battle of Britain was Sir Hugh Dowding.[18] The role of Fighter Command was to repel any attack on Britain from the Luftwaffe, German Air Force. To best complete this mission Dowding had a plan to divide his resources across England. The No. 11 group which covered the southeast of the country was supplied with 12 Hurricane, 6 Spitfire, and 4 Blenheim squadrons. The No. 12 group which covers the East Anglia area was supplied with 5 Hurricane, 5 Spitfire, 2 Blenheim, and 1 Defiant squadrons. The No. 13 group in the north was supplied with 3 Hurricane, 6 Spitfire, 1 Blenheim, and 1 Defiant squadrons. The No. 10 covering the west included 2 Hurricane, and 2 Spitfire squadrons. Many people felt that Dowding should have concentrated all of his best fighters in the No. 11 group as that was the most likely to encounter fighter opposition. Dowding knew that the Battle of Britain would be a war of attrition and to keep a mix of fighters in less dangerous areas as a reserve would be important to the upcoming battle.[19] The Fighter Command had plenty of aircraft to go around with production ramping up, but pilots were much more difficult to replace. At the beginning of the Battle of Britain many squadrons were over-manned but as it dragged on training new pilots became a problem. As training took 6 months there were not enough pilots to have Fighter Command at full strength so the training courses were reduced to 4 weeks with the squadrons left to finish the pilot's training, sometimes with disastrous consequences.[20] Dowding was not the most liked of the leaders in the military and was eventually forced out of his position as the head of Fighter Command on November 17, 1940.[21] At the time no one recognized the importance of his work and how he saved Britain. Most importantly he set up a system of direction and control for his fighters to make the most out of their limited resources. Second, Dowding pushed to limit the support of the French in terms of aircraft that were essential to defending Britain in an air attack; he didn't stop but helped reduce. Third, his careful placement and use of fighter resources prevented being draw into a major battle and having his forces destroyed. His plan to keep fighters in reserve to reinforce the main No. 11 group was essential to this even though it gained much criticism.[22]

Fighter Command and Control System

Radar Stations

Radar Station[23]

At the time Radar was known as Radio Direction Finding and the system that was in use by the British was simple but effective. The initial deployment was High Frequency radio Direction Finding (HF DF) to find the position of a friendly aircraft when out of sight of the controller. As the technology became refined, Fighter Command became experimenting with radar controlled intercepts of unknown targets in 1936.[24] In 1937, the system in use was known as Pip Squeak. This system transmitted a coded DF signal for 14 seconds every minute to allow the controllers to know the identity of each aircraft. To identify the other aircraft not using the Pip Squeak system they turned to physicist Robert Watson-Watt. This new technology was designated RDF which was rapidly developed. In only a few months the system was up and running detecting aircraft out to 58 miles. A string of these radar stations were built on the southern coast in 1936 and became fully operational in 1938.[25] This first chain of 21 stations was called Chain Home and utilized fixed antenna arrays. There was also another set of radar stations called the Chain Home Low stations, of which there were 30, that utilized a rotating antenna for a narrow search beam. These were not as effective as they had less range and could not give altitude information.[26] In addition to these radar advances, an improvement in plane identification was also being worked on. The new system was called IFF, Identification Friend or Foe. The IFF was a small transmitter that gave a distinctive radar blip to allow radar operators to differentiate between friend and foes.[27] When both friendly and enemy planes were spotted on radar that information was then sent to the Filter Room to be assessed.

Observer Corps

Observer Corps[28]

The Observer Corps was a volunteer service meant to fill in the gaps of radar. Radar was successful at looking out to sea but was blind to its back on land. This was the job of the Observer Corps, to track and report the movement of aircraft over land. Volunteers for the Observer Corps used binoculars, telescopes, and makeshift devices to determine the altitude and bearing of enemy aircraft. This technique was trialed in 1925 to outstanding success, after which the program rolled out rapidly to over 100 posts in that year. For the large roll out, a map was divided into 1.2 mile squares which then reported via telephone lines to their respective Observer Corps Group Headquarters. The full scale system across Britain was tested during the 1939 Air Exercises after which the posts were manned unbroken for 6 years until the end of the war.[29]

Fighter Command Operations Room and Filter Room

Bentley Priory Fighter Command and Operations Room[30]

The Fighter Command and Operations Room was manned by the Commander-in-Chief of Fighter Command, Commander-in-Chiefs of the Observer Corps and the Anti Aircraft Command, the liaison officers of Bomber and Coastal Commands, the liaison officer of the Admiralty, and the liaison officer for the Ministry of Home Security. The room housed the plotting table that displayed aircraft over all of the UK and the sea approaches. The Filter Room was located underneath the Fighter Command Operations Room. Its job was to receive all of the plots from the Radar Stations, compile them and cross reference the plots with the IFF plots. These cross referenced plots were then passed upstairs to the Fighter Command Operations Room.[31]

Group and Sector Operations Rooms

The Group Operations Room received radar plots from the Filter Rooms and visual plots from the Observer Corps. The information was analyzed and then used to direct sectors to deal with incoming raids. In the event the Group Operations Room was knocked out in a raid, each Sector Operations Room could be used as the to command center. Each Sector Operations Room had its own plotting tables with radar and Observer Corps plots provided from the Filter Room. When a Sector Operations Room was given notice of an enemy raid a controller would order an aircraft launch and then vector them for an intercept which was confirmed when the formation leader called 'Tally Ho!' which means enemy in sight.[32] To vector the aircraft, the controller needed to know the location of the friendlies which was reported by the Direction-finding Triangulation who received information from the Direction Finding, D/F, stations. The Sector Operations Room also controlled the anti-aircraft guns and Balloon Barrages. As with the aircraft launches, the Sector Controller would alert the guns and balloons to incoming enemy raids to allow them time to position.[33]
