SANTA ANA, Calif., July 28, 2010—The Cessna L-19/O-1 Bird Dog, considered by many aviation experts to be the finest liaison and observation aircraft ever produced, will be onpermanent display at Lyon Air Museum (LAM), based at John Wayne Airport in Orange County, Calif. The plane is painted in the markings of the U.S. Army’s 183rd Reconnaissance Airplane Company (RAC), known as the “Seahorses,” whose pilots flew the planes during the Vietnam War.

“We are very pleased to welcome the Bird Dog as part of our exhibit collection,” said Mark Foster, LAM president. “The plane serves as a tribute to the many brave pilots who flew visual and photo reconnaissance, artillery adjustment, forward air control, and search and rescue missions during wartime.”

The Cessna L-19/O-1 Bird Dog was the first all-metal fixed-wing aircraft ordered for and by the U.S. Army following the separation of the U.S. Army Air Forces from the Army in 1947, when the service became the U.S. Air Force (USAF). In addition to the U.S. Army and USAF, the Bird Dog served with the Unites States Marine Corps (USMC) and 19 foreign countries

The Birddog was first built in 1950 by the Cessna Aircraft Company as a military reconnaissance plane. Between 1950 and 1964, 3,398 airframes were built. Originally called the L-19, these planes saw extensive duty during the Korean War from 1950–53, often in the hands of veteran World War II fighter and bomber pilots. The Bird Dog was re-designated the 0-1 in 1962 and was flown in Vietnam until that war ended in 1975.

The L-19 received the name Bird Dog as a result of a contest held with Cessna employees to name the aircraft. The name was chosen because the role of the army’s new aircraft was to find the enemy and orbit overhead until artillery (or attack aircraft) could be brought to bear. While flying low and close to the battlefield, the pilot would observe the exploding shells and adjust the fire via his radios, in the manner of a bird dog (gun dog) used by game hunters.

The Bird Dog met up with the Seahorses midway during the Vietnam War. The 183rd RAC was organized and activated at Fort Hood, Texas, in 1966 and began their combat tour in June of that year in Vietnam’s Cam Rahn Bay.

The name “Seahorses” derives from the 183rd‘s use of the image of Pegasus, the winged horse of classical mythology, as its symbol.

“When we got to Cam Rahn Bay we were told that the call signs for aviation units had to have a maritime connection,” recalled Mack Gibson, who was the company’s executive officer. “They suggested that we use ‘Driftwood,’ but none of our men were going to be called that. So, we just called Pegasus a sea creature and we became the ‘Seahorses.’”

The mission of the Seahorses was to provide day and night aerial visual reconnaissance of enemy areas for the purpose of terrain study, locating, verifying and marking targets and directing artillery, naval gunfire and helicopter gunships

As the company made nearly daily visual reconnaissance flights above South Vietnam, U.S. combat units began calling the 0-1 Bird Dog spotter planes and their 183rd RAC pilots “the Seahorses.” Replicas of actual sea horses became the company trademark, and silhouettes of the tiny marine animals adorned the wings of all 183rd aircraft.

During the course of the Vietnam War, 469 O-1 Bird Dogs were lost to all causes. The USAF lost 178, the USMC lost seven, and 284 were lost from the U.S. Army, South Vietnamese forces and clandestine operators. Three Bird Dogs were lost to enemy surface-to-air missiles (SAMs).

Gibson said that his company, which is holding its annual reunion in Colorado Springs this September, is proud that the Bird Dog is being honored with a permanent place at Lyon Air Museum.

“The Viet Cong found it hard to get a decent offensive going with Seahorse spotters tracking their every move,” he said.

Following the war, the USAF phased out the O-1 in favor of the O-2, and many O-1s in the United States were sold as surplus. Many O-1s were turned over to the Civil Air Patrol for such duties as aerial search. The L-19/O-1 is a popular ex-military “warbird” with private pilots. As of June, 2009, more than 330 were registered with the Federal Aviation Administration (FAA). Others are owned and operated outside the U.S. by individuals and flying organizations.
