LSM(R)-508 and Targeteer: The Evolution of a Naval Vessel
The history of the vessel known as LSM(R)-508 is a fascinating study in naval adaptability. Originally designed as a specialized landing craft for the final stages of World War II, the ship underwent a dramatic transformation decades later, evolving from a rocket-firing assault vessel into a sophisticated control ship for unmanned drone technology.
Early Service as a Landing Ship Medium (Rocket)
LSM(R)-508 began its journey in June 1945. After departing Houston on June 30, the ship moved to Galveston, Texas, for fitting out. By July 5, it was underway for Charleston, South Carolina, where it received its rocket launchers and underwent necessary alterations. The vessel then shifted to Little Creek, Virginia, on July 31.
The ship's shakedown—a period of trials to ensure the vessel and crew are ready for active duty—took place between August 1 and August 15, 1945. It was during this critical training phase that Japan capitulated, bringing the Pacific War to a close.

Throughout 1946, the ship operated out of Little Creek, the Virginia Capes, and the Caribbean. It conducted extensive training exercises based out of Guantanamo Bay, Cuba, and San Juan, Puerto Rico. Following a period of repairs in Baltimore, Maryland, in July 1946, the ship sailed for Houston in October, transited the Panama Canal on November 30, and arrived in San Diego, California, for inactivation.
The vessel was decommissioned on February 5, 1947, and placed in reserve at San Diego. During its long period of inactivity, it was renamed the Gunnison River on October 1, 1955.
Conversion to the Targeteer (YV-3)
After nearly two decades in reserve and a brief period where it was slated for disposal in 1959, the Gunnison River was reinstated to the Navy list in early 1960. The Navy selected the vessel for a specialized conversion into a drone aircraft catapult control ship.
On May 26, 1960, the ship was reclassified as YV-3 and renamed the Targeteer on June 26, 1960. It was placed in service in March 1961 and officially commissioned on April 7, 1961.
The "World's Smallest Aircraft Carrier"
Homeported in San Diego from 1961 to 1968, the Targeteer operated under the control of the Commander, Fleet Training Group, San Diego. Its primary mission was the launch and recovery of radio-controlled drone aircraft and surface drone unit targets. These assets provided simulated "enemy" aircraft and high-speed surface craft for fleet exercises.
Among these targets were the "Firefish," high-speed radio-controlled boats designed to simulate the PT boat attacks that occurred against the USS Maddox (DD-731) and USS Turner Joy (DD-951) in the Tonkin Gulf. Because of its unique ability to launch and recover these drones, the Targeteer earned the nickname "the world's smallest aircraft carrier."

Final Years and Disposal
The Targeteer utilized the morse-code callsign "N-T-Q-O" and maintained communications via COMTRAPAC Communications. While in port, it tied up at the Fleet Anti-Submarine Warfare School (now Center) in San Diego.
The ship's active service ended on December 31, 1968, when it was decommissioned. It was struck from the Navy list on January 1, 1969, and sold to the American Ship Dismantling Co. of Portland, Oregon, on December 10, 1969, where it was subsequently scrapped.

Frequently Asked Questions
What was the original purpose of LSM(R)-508?
LSM(R)-508 was a Landing Ship Medium (Rocket), designed to provide rocket fire support during amphibious landings.
Why was the Targeteer called "the world's smallest aircraft carrier"?
It earned this nickname because it was equipped to launch and recover radio-controlled drone aircraft, mimicking the functions of a full-sized aircraft carrier on a much smaller scale.
What were "Firefish" surface craft?
Firefish were very fast, radio-controlled boats used as targets to simulate PT boat attacks, specifically based on the events involving the USS Maddox and USS Turner Joy in the Tonkin Gulf.
How long was the ship inactive between its two service periods?
The ship was decommissioned in February 1947 and reinstated in early 1960, remaining inactive for approximately 22 years.
What happened to the ship after its final decommissioning?
After being decommissioned on December 31, 1968, the ship was sold to the American Ship Dismantling Co. in Portland, Oregon, in December 1969 and was scrapped.
