PT-121 was a motor torpedo boat of the United States Navy, built by the Electric Launch Company (ELCO) of Bayonne, New Jersey, launched in 1942, and sunk by air attack in a friendly fire incident on 27 March 1944. [1]
A PT boat was a torpedo-armed fast attack vessel (MTB) used by the United States Navy in World War II. It was small, fast, and inexpensive to build, valued for its maneuverability and speed but hampered at the beginning of the war by ineffective torpedoes, limited armament, and comparatively fragile construction that limited some of the variants to coastal waters.

The United States Navy (USN) is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States. It is the largest and most capable navy in the world and it has been estimated that in terms of tonnage of its active battle fleet alone, it is larger than the next 13 navies combined, which includes 11 U.S. allies or partner nations. With the highest combined battle fleet tonnage and the world's largest aircraft carrier fleet, with eleven in service, and two new carriers under construction. With 319,421 personnel on active duty and 99,616 in the Ready Reserve, the U.S. Navy is the third largest of the U.S. military service branches in terms of personnel. It has 282 deployable combat vessels and more than 3,700 operational aircraft as of March 2018, making it the third-largest air force in the world, after the United States Air Force and the United States Army.
The Electric Launch Company, later renamed Elco Motor Yachts, is a United States boat building and electric motor company that has operated from 1893 to 1949 and from 1987 to the present
On the morning of March 27, 1944, Lt. Crowell C. Hall, USNR, executive officer of Squadron 25, in PT-353 (Ens. George H. Guckert, USNR), with PT-121 (Ens. Richard B. Secrest, USNR), was trying to thread a way through New Britain's reefs to Ewasse, in Bangula Bay, to investigate a reported enemy schooner. At 0745, four P-40s fighters of 78 Squadron, Royal Australian Air Force operating out of Kiriwina, flew over and Lieutenant Hall asked them by radio to investigate the schooner. The aircraft complied, and reported it had been strafed previously and was no longer a worthwhile target. No sooner had the boats turned to leave than they were attacked by four other P-40s of 78 Squadron and a Beaufighter heavy fighter of 30 Squadron RAAF. A second Beaufighter recognized the PTs and throughout the attack attempted to call off the other Beaufighter by radio and to maneuver to head off the P-40s. [1]
New Britain is the largest island in the Bismarck Archipelago of Papua New Guinea. It is separated from the island of New Guinea by the Dampier and Vitiaz Straits and from New Ireland by St. George's Channel. The main towns of New Britain are Rabaul/Kokopo and Kimbe. The island is roughly the size of Taiwan. While the island was part of German New Guinea, it was named Neupommern.
A schooner is a type of sailing ship, as defined by its rig configuration. Typically it has two or more masts, the foremast being slightly shorter than the mainmast.
A fighter aircraft is a military aircraft designed primarily for air-to-air combat against other aircraft, as opposed to bombers and attack aircraft, whose main mission is to attack ground targets. The hallmarks of a fighter are its speed, maneuverability, and small size relative to other combat aircraft.
No order to open fire was given on either boat. After the aircraft made several runs, gunners on the PT-353 fired seven or eight rounds of 40 mm and five rounds of 37 mm, and those on the PT-121 fired seven rounds of 20 mm and three short bursts of .50 caliber gunfire. Lieutenant Hall on the PT-353 and Ensign Secrest on the PT-121 stopped the firing immediately. Both boats burned, exploded, and sank, except for a portion of the bow of the PT-121. Shortly after the attack, two P-40s of the group that had investigated the schooner returned. They dropped a liferaft to the survivors and sent in a radio report of the tragedy. Five hours later, a P-40 guided PT-346 and PT-354 to the survivors. [1]
A lifeboat or life raft is a small, rigid or inflatable boat carried for emergency evacuation in the event of a disaster aboard a ship. Lifeboat drills are required by law on larger commercial ships. Rafts (liferafts) are also used. In the military, a lifeboat may double as a whaleboat, dinghy, or gig. The ship's tenders of cruise ships often double as lifeboats. Recreational sailors usually carry inflatable life rafts, though a few prefer small proactive lifeboats that are harder to sink and can be sailed to safety.
Four officers and four enlisted men were dead; four officers and eight enlisted men were wounded; two PTs were completely destroyed. [1]
In part, the losses were caused by a failure in communication. The message reporting the intended movements of PTs had been placed in the wrong file at 78 Squadron headquarters, so the pilots had not been told that PTs would be operating in the area. In part, the losses were caused by failure of the pilots to recognize the PTs. The first P-40s recognized them and gave them a helping hand. One Beaufighter in the second group recognized them and tried to stop the attack. The other pilots simply mistook them for enemy craft. [1]
After an investigation by the Navy, Ensign Secrest received the Navy Cross. [1]
The Bristol Type 156 Beaufighter is a multi-role aircraft developed during the Second World War by the Bristol Aeroplane Company in the United Kingdom. It was originally conceived as a heavy fighter variant of the Bristol Beaufort torpedo bomber. The Beaufighter proved to be an effective night fighter, which came into service with the Royal Air Force (RAF) during the Battle of Britain, its large size allowing it to carry heavy armament and early airborne interception radar without major performance penalties.
The Westland Whirlwind was a British twin-engined heavy fighter developed by Westland Aircraft. A contemporary of the Supermarine Spitfire and Hawker Hurricane, it was the first single-seat, twin-engined, cannon-armed fighter of the Royal Air Force.
PT-109 was a PT boat last commanded by Lieutenant John F. Kennedy, future United States President, in the Pacific Theater during World War II. His actions to save his surviving crew after the sinking of PT-109 made him a war hero. PT-109's collision with a Japanese Destroyer contributed to Kennedy's long-term back problems and required months of hospitalization at Chelsea Naval Hospital. Kennedy's post-war campaigns for elected office referred often to his service on the PT-109.
A fighter-bomber is a fighter aircraft that has been modified, or used primarily, as a light bomber or attack aircraft. It differs from bomber and attack aircraft primarily in its origins, as a fighter that has been adapted into other roles, whereas bombers and attack aircraft are developed specifically for bombing and attack roles.
They Were Expendable is a 1945 American war film directed by John Ford and starring Robert Montgomery and John Wayne and featuring Donna Reed. The film is based on the 1942 book by William L. White, relating the story of the exploits of Motor Torpedo Boat Squadron Three, a PT boat unit defending the Philippines against Japanese invasion during the Battle of the Philippines (1941–42) in World War II.
McHale's Navy is an American sitcom starring Ernest Borgnine that aired 138 half-hour episodes over four seasons, from October 11, 1962, to April 12, 1966, on the ABC television network. The series was filmed in black and white and originated from an hour drama entitled Seven Against the Sea, broadcast on April 3, 1962.
The Second Battle of Cárdenas was a secondary naval engagement of the Spanish–American War fought on 11 May 1898 in the port of Cárdenas, Cuba, between an American squadron of 5 ships under Captain Chapman C. Todd and 3 small Spanish vessels under Mariano Mateu. The battle resulted in an unusually costly American reverse that dissuaded the U.S. Navy from undertaking further attacks on the port.
PT-337 was a PT-103-class motor torpedo boat that was sunk in action during the Pacific Theater of World War II in Hansa Bay, New Guinea on March 7, 1944.
German submarine U-134 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. She was laid down on 6 September 1940 by Bremer Vulkan in Bremen-Vegesack as yard number 13 and commissioned on 26 July 1941. In seven patrols, U-134 sank three ships for a total of 12,147 gross register tons (GRT).
Motor Torpedo Boat PT-59 was a PT-20-class Motor Torpedo Boat of the United States Navy, built by the Electric Launch Company of Bayonne, New Jersey. The boat was laid down as Motor Boat Submarine Chaser PTC-27, and was reclassified as BPT-11 when assigned to transfer to Britain under Lend-Lease. However, this was cancelled, and she was reclassified as PT-59 prior to launch on 8 October 1941, and was completed on 5 March 1942.
This is the complete order of battle of Allied and Japanese forces during the Borneo campaign of 1945. As the campaign was fought in three geographically separate areas and the same air and naval units supported more than one of these battles the order of battle is split into the three areas.
No. 78 Squadron was a Royal Australian Air Force (RAAF) fighter squadron of World War II. It was formed in July 1943 as part of expansion of the RAAF's fighter force, and was assigned to mobile striking forces for the duration of the war.
The 37 mm Automatic Gun, M4, known as the T9 during development, was a 37 mm (1.46 in) recoil-operated autocannon designed by Browning Arms Company. The weapon, which was built by Colt, entered service in 1942. It was used in the Bell P-39 Airacobra and P-63 Kingcobra.
Knyaz Suvorov was a Borodino-class pre-dreadnought battleship built for the Imperial Russian Navy in the first decade of the 20th century. Named after the 18th-century Russian general Prince (Knyaz) Alexander Suvorov, the ship was completed after the beginning of the Russo-Japanese War in 1904. She became the flagship of Vice Admiral Zinovy Rozhestvensky, commander of the Second Pacific Squadron that was sent to the Far East a few months after her completion to break the Japanese blockade of Port Arthur. The Japanese captured the port while the squadron was in transit and their destination was changed to Vladivostok. Knyaz Suvorov was sunk during the Battle of Tsushima on 27 May 1905. During the battle, the ship fell out of the main battle line after a shell hit her bridge, killing her helmsman and wounding her captain and Rozhestvensky. She was eventually torpedoed and sunk by Japanese torpedo boats; other than the 20 wounded officers evacuated by a destroyer there were no survivors.
PT-346 was an 80 ft Electric Launch Company (Elco) motor torpedo boat which suffered the worst PT-boat friendly-fire casualties of World War II, with nine men killed and nine wounded by airstrike.
Huckins Yacht Corporation is one of the oldest boat builders in the United States. The company is located on the Ortega River in Jacksonville, Florida, and is run by its third-generation owners, Cindy and Buddy Purcell. Huckins manufactures custom yachts ranging from 40 to 90 feet that combine classic design and traditional workmanship with modern technology and amenities. It has built a total of 457 yachts during its 80 years of operation, crafting vessels one at a time.
The West Indies Squadron, or the West Indies Station, was a United States Navy squadron that operated in the West Indies in the early nineteenth century. It was formed due to the need to suppress piracy in the Caribbean Sea, the Antilles and the Gulf of Mexico region of the Atlantic Ocean. This unit later engaged in the Second Seminole War until being combined with the Home Squadron in 1842. From 1822 to 1826 the squadron was based out of Saint Thomas Island until the Pensacola Naval Yard was constructed.
The West Indies Anti-Piracy Operations refer to the United States Navy presence in the Antilles, and surrounding waters, which fought against pirates. Between 1817 and 1825, the American West Indies Squadron constantly pursued pirates on sea and land, primarily around Cuba and Puerto Rico. After the capture of Roberto Cofresi in 1825, acts of piracy became rare and the operation was considered a success although limited occurrences went on until slightly after the start of the 20th-century.
Piso Point is a former Japanese naval base throughout World War II which is located at the eastern portion of the Davao Gulf, across from Davao City, Philippines. It was also a harbor for Japanese suicide boats which had been harassing American shipping in the Davao Gulf. During the liberation of the Philippines from the Japanese on May 14, 1945, many of the Japanese suicide boats were annihilated by the U.S. Navy.
