The top of an period: USAF retires recon movie digital camera used on U-2 Dragon Girl spy airplane: Digital Pictures Evaluate

Not many planes have the illustrious historical past of the Lockheed-Martin U-2 spy airplane. Flown initially by the Central Intelligence Company (CIA) and later america Air Power, the U-2, nicknamed ‘Dragon Girl,’ has carried out high-altitude reconnaissance from greater than 21,000m (70,000′). The airplane was first launched in 1956 and stays in service. The unique airplane ceased manufacturing in 1989, succeeded by newer U-2S and TU-2S fashions.

At Beale Air Power Base in California, a U-2 Dragon Girl has flown the skies as a part of the Air Power’s ninth Reconnaissance Wing since 1974 with an onboard Optical Bar Digicam (OBC). Nonetheless, on June 24, the airplane flew its remaining sortie with the OBC. Upon touchdown, Air Power technicians eliminated the OBC sensor, marking the top of an period.

The OBC is a moist movie digital camera, so the removing of the OBC from Beale’s Dragon Girl additionally marks the top of movie processing on the ninth Reconnaissance Wing. It is the top of an period. The ultimate flight was piloted by U.S. Air Power Lt. Col. Ralph Shoukry. Beale is dwelling to many spy planes, together with RQ-4 International Hawk spy planes and T-38 Talon trainers. The bottom additionally housed SR-71 Blackbirds.

Beale’s U-2 squadron has now embraced digital pictures. ‘This occasion closes a decades-long chapter for Beale Air Power Base and movie processing, and it opens one other chapter into the digital world,’ stated Adam Marigliani, engineering help specialist for Collins Aerospace, a companion with Beale’s intelligence operations.

On June 24, the U-2 and its onboard OBC took its remaining flight. Members of the ninth Intelligence Squadron, Collins Aerospace and the first Coaching Squadron have been readily available to witness the ultimate flight.

‘The OBC mission operated out of Beale for near 52 years, with the primary U-2 OBC deploying from Beale in 1974,’ stated 2nd Lt. Hailey M. Toledo. ‘Pulled from the SR-71 [Blackbird], the OBC was modified and flight examined to help the U-2 platform, changing the long-standing IRIS sensor. Whereas the IRIS’s 24-inch focal size supplied widespread protection, the OBC’s 30-inch focal size allowed for considerably better decision.’

Regardless of being almost 70 years outdated, the U-2 Dragon Girl stays an essential a part of US surveillance operations, even when its movie pictures days are over. The U-2 will probably be outfitted with digital sensor packages now. Newer planes have arrived on the scene however have but to supplant the single-jet recon airplane. U-2 planes have flown worldwide, together with heavy use all through the Chilly Battle and through a number of NATO operations. The U-2 has additionally been used for scientific analysis and communications, not simply navy surveillance. The U-2 has additionally been utilized by the Royal Air Power and the Republic of China Air Power.

The U-2 Dragon Girl and OBC take off for his or her remaining flight collectively.

The OBC is a panoramic digital camera that strikes forwards and backwards to seize giant pictures. The rotating spy digital camera spins movie via a curler cage, permitting it to seize broad panoramic images. In a virtually 20-year-old press launch, the USAF says that the OBC captured one body each 6.8 seconds when used on the U-2 recon airplane. Grasp Sgt. Charles Davis of the ninth Reconnaissance Wing stated, ‘Every roll of OBC movie is 5 inches broad and 10,500 toes lengthy with every body of images measuring greater than 6 toes lengthy. With a whole roll of movie, the digital camera can take about 1,600 frames in a single mission. Every body covers roughly 110 sq. nautical miles in a panoramic horizon-to-horizon format. Principally, a roll of movie can shoot an space the scale of Colorado.’ Davis continued, ‘This plane and this sensor have a lot historical past that it’s nearly overwhelming to cease and take into consideration the locations these cameras have been and the issues they will need to have seen.’

‘All U-2 pilots will retain the information and expertise to make use of the sensor via a wide range of mission units and operation places to fulfill precedence intelligence assortment wants of the geographic combatant commanders as tasked,’ stated Lt. Col. James Gaiser, commander of the 99th Reconnaissance Squadron. ‘The U-2 retains the aptitude to fly the OBC mission worldwide and, if known as upon, to execute in a dynamic power employment capability… With a rising want for extra various assortment necessities, the U-2 program will evolve to keep up fight relevance with a wide range of C5ISR-T capabilities and fight air forces integration roles.’

The OBC might return into service as wanted and can stay out there when known as upon. As of now, no good digital alternative has been developed. Digital imaging expertise does not fairly match the resolving energy of the OBC.
