[This is not the place for a discussion of bomb lines and/or marking techniques,nor the evolution of forward air control,sufficeth to say that all these things took time to develop.
We live in an era when CAS has become one of the principle roles of any Air Force but the communcations and weapons systems to achieve the sort of results we see on the news (or Liveleak or Youtube) simply didn't exist during WW2.
I cant see why this is not the place to discuss FACs. Its such an integral part of delivering effective CAS, so why not discuss it.
FACs is considered to have been invented during the American Civil War in the Union Army Baloon Corps, by its commander Thaddeus Lowe. Its most effective applications were during the sieges of Richmond and Petersburg, when Union artillery was accurately directed by the balloon crews using portable telegraph
Im not sure if there was any effective FACs in the allied camp at the outbreak of the war, and that certainly shows in the abysmal showing made in the first years of the war. Conversely I am fairly sure the Germans had an effective FACs system grafted or embedded into their unit command structures. i hav idea how it worked or how it was organized, but you dont get the level of effectiveness that they di by having aircraft flying around the battle unco-ordinated (in an immeediate sense).
For the allies, by 1943, the situation had completely changed. Significant strides were made in defining the role of airpower in close support of ground forces. Forward air control concepts were tried with limited success by the South African Air Force as part of the Royal Air Force in the African campaigns but it wasn"t until the war in Italy that the concepts of ground and airborne forward air controlling were well defined.
The Rover system was developed by the British and adopted by the Americans. A Rover unit consisted of an RAF controller, and an Army Air Liaison Officer, and VHF radio for aircraft communications. Their function was to apply air power to targets, often fleeting, close to the front line. A fundamental feature of the system was use of waves of strike aircraft, with pre-briefed assigned targets but they were required to orbit near the line of battle for 3-20 minutes, subject to Rover preemption and use against fleeting targets of higher priority or urgency. If the Rovers did not direct the fighter-bombers, the latter attacked their pre-briefed targets. U.S. commanders, impressed by the British at the Salerno landings, adapted their own doctrine to include many features of the British system. One important aspect of the Rover system was the willingness to use large numbers of tactical attack aircraft, which were only available after air supremacy had been achieved in the area.
The Rover system was complimented by the use of airborne Forward Air Controllers flying light aircraft (British Lysanders and USAAF L-5 Sentinels). These FACs used the collective call sign Horsefly. Success of the Horsefly operations was tempered by inadequate communications equipment and extreme vulnerability to hostile air-to-air action and Anti-Aircraft Artillery (AAA).
For the Normandy invasion each beachhead was assigned an LST with a combined Army and Air Force control element to coordinate Army requirements for close air support. Rover parties went ashore with all the ground forces. However, it wasn"t until the fall of 1944 that Horsefly-type FACing became common. Increased resources and the full use of the expanded air-ground liaison teams produced a functional system of airborne FACs.
There are many stories of individual heroism by Forward Air Controllers in WW II but perhaps none is more impressive than the story about Captain James E. Parker. Captain Parker was in charge of the air support party that had been rushed to Bastogne on 18 December 1944. It was his job to integrate Close Air Support (CAS) into the fight throughout the siege. Captain Parker, a veteran fighter-bomber pilot with considerable experience in both the Pacific and European theaters, was also an experienced Forward Air Controller. Parker talked to flight leaders en route to Bastogne, gave them approach instructions, and helped them identify intended targets. P-47s came in low and fast, catching the Germans by surprise. On more than one occasion, ground troops received CAS within fifteen minutes of requesting an air strike. Enemy flak was heavy and elusive, with German batteries apparently moving from position to position around the Bastogne perimeter. On 28-29 December, Captain Parker coordinated a series of combined arms air-artillery attacks that finally silenced the threat and enabled the American Army to break the siege.
At the conclusion of WWII the US seems to have forgotten many of the hard lessons of WWII and in their haste to demobilize disbanded the airborne Forward Air Controller concept and relegated it to a ground based system using radio equipped jeeps. This is where the system was at the beginning of the Korean War, and it explains the generally lower accuracy rates achieved by the USAF and USN for the early parts of that conflict.
It was probably true that FACS did not exist in the allied armies at the beginning of the war
It's also noteworthy that the multi role aircraft is the backbone of most modern Air Forces and this is a direct descendant of the WW2 fighter bombers,aircraft forced into multiple roles for which they were never intended. It is easily forgotten that the Typhoon was designed as an air superiority fighter.
True, but some adapted to the job better than others. I dont know all that much about Typoons, but Furies and fireflies achieved impressive results during the Korean war
The dive bomber was a dead end,useful in its time,but whose days were always numbered.
Absolutely.
