     The President of the United States takes pleasure in presenting the MEDAL OF HONOR to

FIRST LIEUTENANT JAMES E. SWETT
UNITED STATES MARINE CORPS RESERVE
 

for service as set forth in the following

CITATION:

For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty, as a division leader in Marine Fighting Squadron TWO TWENTY-ONE in action against enemy Japanese aerial forces in the Solomon Islands Area, April 7, 1943. In a daring flight to intercept a wave of 150 Japanese planes, First Lieutenant Swett unhesitatingly hurled his four-plane division into action against a formation of fifteen enemy bombers and during his dive personally exploded three hostile planes in mid-air with accurate and deadly fire. Although separated from his division while clearing the heavy concentration of anti-aircraft fire, he boldly attacked six enemy bombers, engaged the first four in turn, and unaided, shot them down in flames. Exhausting his ammunition as he closed the fifth Japanese bomber, he relentlessly drove his attack against terrific opposition which partially disabled his engine, shattered the windscreen and slashed his face. In spite of this, he brought his battered plane down with skillful precision in the water off Tulagi without further injury. The superb airmanship and tenacious fighting spirit which enabled First Lieutenant Swett to destroy eight enemy bombers in a single flight were in keeping with the highest traditions of the United States Naval Service.

/S/ FRANKLIN D. ROOSEVELT

James Elms Swett was born at Seattle, Washington, 15 June 1920, the first of three children of George Elms Swett, an electrical engineer and U.S. Marine Corps reservist, and Nellie Emily Burns Swett. He grew up in San Mateo, California, where he attended San Mateo High School and the College of San Mateo. While in college, Swett learned to fly through the Civilian Pilot Training Program.

Swett enlisted in the United States Navy as a Seaman 2nd Class, 26 August 1941. He had brown hair and blue eyes, was 5 feet, 11 inches (1.803 meters) tall and weighed 154 pounds (69.9 kilograms). Seaman Swett was assigned to flight training as an Aviation Cadet at NAS Corpus Christi, Texas. While in training, Sweet elected to serve as a U.S. Marine Corps officer. On completion of flight training, James Swett was awarded the gold wings of a Naval Aviator and commissioned a Second Lieutenant, United States Marine Corps Reserve, 1 April 1942. He was then sent to MCAS Quantico at Quantico, Virginia, for advanced training.

In July 1942, 2nd Lieutenant Swett was placed under arrest for a period of ten days for “diving and zooming over traffic” below 500 feet (152 meters), along U.S. Route 1. He was then transferred to an air station in Florida.

Swett was next assigned to Marine Fighting Squadron 221 (VMF-221), Marine Air Group 21 (MAG-21), 1st Marine Air Wing, Fleet Marine Force. In March 1943, the squadron deployed from Hawaii to the South Pacific aboard the Bogue-class escort carrier USS Nassau (CVE-16), arriving at Espiritu Santo, New Hebrides, in late March. VMF-221 then flew on to Henderson Field, Guadalcanal, in the Solomon Islands.

On the morning of 7 April 1943, Lieutenant Swett led a four-plane flight of Wildcats on a patrol, then returned to refuel at Henderson Field. While his fighter, Grumman F4F-4 Wildcat, Bu. No. 12084, was being serviced, word came of a large group of enemy aircraft approaching from the north. Swett and his flight joined a number of other fighters to intercept the attacking enemy aircraft.

Near the Russell Islands, about 30 miles (48 kilometers) northwest of Guadalcanal, the American fighters came in contact with an estimated 150 enemy aircraft. Swett, in combat for the first time, quickly engaged three Aichi D3A Type 99 (American reporting name, “Val”) dive bombers. He shot them down. Becoming separated from his flight, he continued to engage the enemy, shooting down several more. His right wing was damaged by American anti-aircraft guns, but he continued. Having shot down seven Vals, he engaged an eighth. The Val’s gunner fired his two 7.7 mm machine guns in defense. By this time, Swett was running out of ammunition, but his final bullets killed the enemy gunner and set the Aichi on fire. Machine gun bullets fired from the Val damaged his windshield, punctured an engine oil cooler and set the Wildcat on fire.

Unable to make it back to Henderson, Swett ditched in the ocean near Tulagi. The airplane quickly sank. It was about 25 feet (7 meters) down before Swett was able to escape from the Wildcat’s cockpit. He was picked up by a U.S. Coast Guard patrol boat. Lieutenant Swett was listed as wounded in action.

During only fifteen minutes, 2nd Lieutenant Swett destroyed seven enemy aircraft and damaged an eighth.¹ He had become an “Ace in One Day.”

Swett was promoted to 1st Lieutenant and transitioned to the Chance Vought F4U-1 Corsair. He shot down four Mitsubishi G4M “Betty” twin-engine medium bombers and an A6M Zero, before being shot down again near New Georgia, 10 July 1943. He returned to combat in October, shot down two more Val dive bombers and a Kawasaki Ki-61 Hien Type 3 fighter, known to Allied forces as “Tony.”

During a ceremony held at Espiritu Santo, 10 October 1943, Major General Ralph Johnson Mitchell, commanding the 1st Marine Air Wing, presented First Lieutenant James Elms Swett, United States Marine Corps Reserve, the Medal of Honor.

In 1944, Captain Swett was returned to the United States, and was training with VMF-221 at MCAS Santa Barbara, California. He would meet President Franklin D. Roosevelt at the White House during the Spring.

Captain Swett married Miss Lois Aileen Anderson 22 January 1944 at St. Paul’s Episcopal Church in Burlingame, California. They would later have two sons, both of whom would go on to become Marine Corps officers.

After retraining in Southern California, VMF-221 returned to the War, assigned to the Essex-class aircraft carrier USS Bunker Hill (CV-17) in the western Pacific.

On the morning of 11 May 1945, Captain Swett was flying a combat air patrol in an F4U-1D Corsair, when the fleet was attacked by kamikaze suicide aircraft. Swett shot down a Yokosuka D4Y Suisei (“Judy”) dive bomber.

During this attack, Bunker Hill was hit by two successive kamikazes and suffered catastrophic damage. 346 men were killed in action, 43 missing in action and 264 wounded. The carrier would survive, but was out of action for the remainder of the war.

Unable to land aboard their carrier, Captain Swett organized the airplanes still airborne and led them to USS Enterprise (CV-6).

During World War II, Major Swett flew 103 combat missions. He is officially credited with 15.5 aerial victories.

Following World War II, Major Swett remained in the Marine Corps Reserve. In 1949, he took command of Marine Fighting Squadron 141 (VMF-141) at NAS Oakland. He was recalled to active duty during the Korean War, but was not sent to the war zone.

James Swett rose to the rank of Colonel. He retired from the Marine Corps in 1970.

In addition to the Medal of Honor, during his career in the Marine Corps, Colonel Swett was awarded the Distinguished Flying Cross with gold star (2 awards); Purple Heart with gold star (2 awards); Air Medal with 4 gold stars (5 awards); Navy Combat Action Ribbon; Presidential Unit Citation with 2 bronze stars (3 awards); Navy Unit Commendation Ribbon; Asiatic-Pacific Campaign Medal with 1 gold star and 1 silver star (6 campaigns); World War II Victory medal; and the Armed Forces Reserve Medal with silver hourglass device (20 years of service).

Colonel James Elms Swett, United States Marine Corps Reserve (Retired), died at Mercy Medical Center in Redding, California, 18 January 2009, at the age of 88 years. He was buried at the Northern California Veterans Cemetery, Igo, California.

The Grumman F4F-4 Wildcat was a single-engine, single place mid-wing monoplane with retractable landing gear, designed for operations from United States Navy aircraft carriers. The wings could be fold alongside the fuselage for storage.

The F4F-4 was 28 feet, 10-5/8 inches (8.804 meters) long with a wingspan of 38 feet, 0 inches (11.582 meters) and height of 12 feet, 1-3/8 inches (3.693 meters). The Wildcat’s wing had 0° angle of incidence. The fixed, inner wing has 0° dihedral, while the outer wing panels have 5° dihedral. There is no sweep. The width of the airplane with its wings folded was 14 feet, 6 inches (4.420 meters). The fighter’s empty weight was 5,895 pounds (2,674 kilograms), and the gross weight, 7,975 pounds (3,618 kilograms).

The F4F-4 was powered by an air-cooled, supercharged, 1,829.399-cubic-inch-displacement (29.98 liter) Pratt & Whitney Twin WaspSSC7-G (R-1830-86) two-row, fourteen cylinder radial engine with a compression ratio of 6.7:1. The R-1830-86 was rated at 1,100 horsepower at 2,550 r.p.m. at 3,500 feet (1,067 meters), 1,000 horsepower at 2,550 r.p.m. at 19,000 feet (5,791 meters), and 1,200 horsepower at 2,700 r.p.m. for takeoff, burning 100-octane gasoline. The engine drove a three-bladed Curtiss Electric propeller with a diameter of 9 feet, 9 inches (2.972 meters) through a 3:2 gear reduction. The R-1830-86 was 5 feet, 7.44 inches (1.713 meters) long, 44 feet, 0.19 inches (1.224 meters) in diameter, and weighed 1,560 pounds (708 kilograms).

The F4F-4 Wildcat had a maximum speed 275.0 miles per hour (442.6 kilometers per hour) at Sea Level, and 318.0 miles per hour (511.8 kilometers per hour) at 19,400 feet (5,913 meters). Its service ceiling was 34,800 feet (10,607 meters), and it had a maximum range of 765 miles (1,231 kilometers).

The F4F-4 was armed with six air-cooled Browning AN-M2 .50-caliber machine guns mounted in the wings with 1,440 rounds of ammunition.

Between February 1940 and August 1945, 7,898 Wildcats were produced by the Grumman Aircraft Engineering Corporation, Bethpage, New York, and General Motors Eastern Aircraft Division at Linden, New Jersey.

¹ Various reliable sources give different values for the number of enemy aircraft shot down by 2nd Lieutenant Swett on 7 May 1943, with the most common being five. Swett claimed eight destroyed, and this is reflected in his Medal of Honor citation. The intelligence officer who investigated determined that his claims were valid. The USMC History Division credits seven enemy aircraft destroyed: “Colonel James Elms Swett, of San Mateo, California, earned the Medal of Honor in World War II for shooting down seven Japanese bombers within 15 minutes.”

7 April 1924

Major de Infanteria aviador António Jacinto da Silva Brito Pais and tenente de Engenharia José Manuel Sarmento de Beires, Serviço Aeronáutico Militar.

7 April 1924: At 6:02 a.m., local time, Major de Infanteria aviador António Jacinto da Silva Brito Pais and tenente de Engenharia José Manuel Sarmento de Beires departed Vila Nova Milfontes on the western coast of Portugal, enroute to Macau, the Portuguese colony on the southeast coast of China. This was intended as a step toward an eventual around-the-world flight, a reminder of the Portuguese voyages of discovery of the 15th and 16th centuries.

Bréguet Type 16 Bn. 2, Pátria.

Their route of flight was:

Stage 1: 7 April, Vila Nova Milfontes, Portugal, to Málaga, Andalusia, Spain. 4 hours, 30 minutes (4:30).

Stage 2: 9 April, Málaga to Oran, French Algeria. 2:45.

Stage 3: 12 April, Oran to Tunis, French Tunisia. 6:50.

Stage 4: 14 April, Tunis to Tripoli, Italian Libya. 6:50.

Stage 5: 16 April, Tripoli to Al-Khums, Italian Libya. 4:00.

Stage 6: 18 April, Al-Khums to Benghazi, Italian Libya. 6:18.

Stage 7: 20 April, Benghazi to Cairo, Kingdom of Egypt. 9:15.

Stage 8: 23 April, Cairo to Riyaq, Greater Lebanon. 5:10.

Stage 9: 26 April, Riyaq to Baghdad, Kingdom of Iraq. 6:00.

Stage 10: 27 April, Baghdad to Bushehr, Persia. 6:05.

Stage 11: 2 May, Bushehr to Bandar Abbas, Persia. 4:31.

Stage 12: 3 May, Bandar Abbas to Chabahar, Persia. 3:30.

Stage 13: 4 May, Chabahar to Karachi, Sindh. 6:29.

Stage 14: 7 May, Karachi to N. 26° 13′, E. 72° 58″ (near Pipar Road, Jodhpur, Rajputana). 5:20.

Route of the Lisboa–Macau Raid 1924

On 7 May, Pátria departed Karachi (in what is now Pakistan) at 6:18 a.m., enroute to Agra, British India. During the flight, water used as engine coolant began leaking from the radiator and the engine temperature started to rise, requiring a reduction in power. Eventually, the airplane was unable to maintain altitude and the crew began a gradual descent. Near the village of Pipar Road, they sighted an open field that seemed suitable for landing. Just before touchdown the airplane was caught by a gust of wind and crashed. The crew received only minor injuries, but their airplane was heavily damaged. It was impractical to repair so far from a major city, so it was abandoned.

Brito Pais, Sarmento de Beires and Gouveia walked back to Karachi, where they continued their journey by train.

The wreck of Pátria was eventually shipped back to Portugal. Its Renault 12 Fe V-12 engine is in the collection of the Museo do Ar at Base Aérea de Sintra, Sintra, Portugal.

De Havilland DH.9A Pátria II.

Several weeks later, they acquired another airplane, a 1920 de Havilland DH.9A powered by a Liberty L-12 engine, which they named Pátria II.

Pátria II could carry only two, so Gouveia had to continue by train. In 10 additional stages, Brito Pais and Sarmento de Beires finally arrived at Macau, 20 June 1924, but after overflying the city, crashed inside Chinese territory. The two aviators, again not seriously hurt, had to walk until they reached the British colony of Hong Kong. Their journey covered 16,760 kilometers (10,414 miles) in 117 hours, 41 minutes flight time.

The airplane used for the first half of this journey was an Avion Bréguet Type 16 Bn. 2 (also designated Bre. 16 Bn. 2), a military aircraft produced by France. The airplane had been purchased by the government of Portugal for a series of long-range flights based on the recommendation of Brito Pais and Sarmento de Beres, both officers in the Serviço Aeronáutico Militar, Portugal’s military air service. It was built in France by the Société Anonyme des Ateliers d’Aviation Louis Bréguet and shipped, knocked down, to Amadora, near Lisbon, where it was assembled. It made its first flight 22 September 1921.

Brito Pais named the airplane Pátria. The phrase, ESTA É A DITOSA PÁTRIA MINHA AMADA, was painted on both sides of the fuselage. This is a line from a poem, Os Luisíades, written by Luís Vaz de Camõs and published in 1572. Translated, it means, “This is my beloved Homeland.”

In November, the new airplane was seriously damaged in a storm. Repairs were not begun until June 1922. On 28 June 1923, the Bre. 16 crashed, but was again repaired and made its next flight 26 October 1923.

The Bréguet Type 16 Bn. 2 is a single-engine, two-place, three-bay biplane, designed toward the end of World War I as a night bomber. It had fixed, two-wheel landing gear with a tail skid. The Bre. 16 Bn. 2 was 9.550 meters (31 feet, 4 inches) long, with a wingspan of 17.000 meters (55 feet, 9.3 inches), and chord of  2.350 meters (7 feet, 8.5 inches). The wings were of equal span. The upper wing was staggered slightly behind lower wing. Both upper and lower wings are equipped with ailerons. The wings are swept aft approximately 3°. The lower wing has no dihedral, while the upper wing has approximately 3° dihedral.  Wing area is variously reported as 72, 73.5 or 75.50 square meters (775, 791.1 or 812.68 square feet). The bomber had an empty weight of 1,268 kilograms (2,862 pounds) and gross weight of 2,398 kilograms (5,287 pounds). Bréguet informed Brito Pais and Sarmento de Beires that the Type 16’s structure was capable of safely supporting 2,719.5 kilograms (5,995.5 pounds) total weight.

The Type 16 was powered by a water-cooled, normally aspirated, 22.089 liter (1,347.973 cubic inch Renault 12 Fe, a 50° single-overhead-cam, direct-drive V-12 engine with 2 valves per cylinder and a compression ratio of 5.0:1. The 12 Fe produced 305 chavel vapeur (301 horsepower) at 1,550 r.p.m., and 312 chavel vapeur (308 horsepower) at 1,600 r.p.m. The engine was 2.057 meters (6 feet, 9 inches) long, 1.124 meters (3 feet, 8.25 inches) wide and 1.372 meters (3 feet, 8.8 inches) high. It weighed 369 kilograms (813.5 pounds).

The Bre. 16 Bn. 2 had a cruise speed of 140 kilometers per hour (87 miles per hour) and maximum speed of 160 kilometers per hour (99 miles per hour) at Sea Level. Its service ceiling was 4,600 meters (15,092 feet), and normal range was 900 kilometers (559 miles).

Approximately 200 Type 16 airplanes were built.

Operation Teapot HA fireball, 6 April 1955. (U.S. Air Force)
Operation Teapot HA fireball, 6 April 1955. (U.S. Air Force)

6 April 1955: At 10:00:04.1 a.m. local time (1800 GMT), a Convair B-36H assigned to the 4925th Test Group (Atomic) at Kirtland Air Force Base, New Mexico dropped an atomic weapon from 42,000 feet (12,802 meters) over the Nevada Test Site, Area 1. The bomb was parachute-retarded to slow its fall so that the bomber could escape its blast effects.

The weapon was a test device produced by the Los Alamos Scientific Laboratory to investigate its use as an air-to-air anti-aircraft missile warhead. The bomb detonated at 36,620 feet (11,162 meters) with an explosive force of 3.2 kilotons. Because of the altitude of the explosion, there was no significant fallout.

All test observers (with goggles) agreed that the fireball appeared more intensely bright than in events of similar yield fired at lower altitude.

The warhead was designed at the Los Alamos Scientific Laboratory (LASL) in New Mexico and was similar to the Wasp Prime device, which had been detonated earlier in the Operation Teapot test series. It used a spherical implosion system. The warhead was a 17-inch (43.2 centimeters) diameter sphere weighing approximately 125 pounds (56.7 kilograms). It was placed inside a Mark 5 bomb case which weighed 1,085 pounds (492.2 kilograms).

This was the only bomb dropped by parachute at the Nevada Test Site.

The Convair B-36H Peacemaker was the definitive version of the ten engine bomber, with 156 B-36H/RB-36H built out of the total production of 383 Peacemakers. It is similar to the previous B-36F variant, though with a second flight engineer’s position, a revised crew compartment, and improved radar controlling the two 20 mm autocannons in the tail turret.

The B-36H was 162 feet, 1 inch (49.403 meters) long with a wingspan of 230 feet (70.104 meters) and overall height of 46 feet, 8 inches (14.224 meters). The total area of its wings was 4,772 square feet (443.3 square meters). The wings’ leading edges were swept aft 15° 5′ 39″. Their angle of incidence was 3°, with -2° twist and 2° dihedral. The empty weight of the B-36H was 165,887pounds (75,245 kilograms) and the maximum takeoff weight is 357,500 pounds (162,159 kilograms).

The B-36H has ten engines. There are six air-cooled, supercharged 4,362.49 cubic-inch-displacement (71.49 liter) Pratt & Whitney Wasp Major C6 (R-4360-53) four-row, 28-cylinder radial engines placed inside the wings in a pusher configuration. These had a compression ratio of 6.7:1 and required 115/145 aviation gasoline. The R-4360-53 had a Normal Power rating of 2,800 horsepower at 2,600 r.p.m. Its Military Power rating was 3,500 horsepower at 2,800 r.p.m., and 3,800 horsepower at 2,800 r.p.m. with water injection—the same for Takeoff. The engines turned three-bladed Curtiss Electric constant-speed, reversible propellers with a diameter of 19 feet, 0 inches (5.791 meters) through a 0.375:1 gear reduction. The R-4360-53 is 9 feet, 9.00 inches (2.972 meters) long, 4 feet, 7.00 inches (1.397 meters) in diameter, and weighs 4,040 pounds (1,832.5 kilograms).

Four General Electric J47-GE-19 turbojet engines are suspended under the wings in two-engine pods. The J47 is a  single-shaft axial-flow turbojet engine with a 12-stage compressor section, 8 combustion chambers, and single-stage turbine. The J47-GE-19 was modified to run on gasoline and was rated at 5,200 pounds of thrust (23.131 kilonewtons).

The B-36H was the fastest variant of the Peacemaker series, with a cruise speed of  216 knots (249 miles per hour/400 kilometers per hour) and a maximum speed of 382 knots (440 miles per hour/707 kilometers per hour) at 35,500 feet (10,820 meters). The service ceiling was 47,000 feet (14,326 meters) and its combat radius was 3,190 nautical miles (3,671 statute miles/5,908 kilometers). The ferry range was 7,120 nautical miles (8,194 statute miles/13,186 kilometers).

The B-36H has six remotely-controlled retractable gun turrets mounting two M24A1 20 mm autocannon, each, with 600 rounds of ammunition per gun. The tail turret was radar-controlled, and another 2 guns were mounted in the nose.

The B-36 was designed during World War II, when nuclear weapons were unknown to the manufacturer. The bomber was built to carry up to 86,000 pounds (39,009 kilograms) of conventional bombs in fours bomb bays. It could carry two 43,000 pound ( kilogram) T-12 Cloudmakers, a conventional explosive earth-penetrating bomb, or several Mk.15 thermonuclear bombs. By combining the bomb bays, one Mk.17 25-megaton thermonuclear bomb could be carried.

April 6, 1949: Lieutenant Stewart Ross Graham, United States Coast Guard, and his crewman, Aviation Metalsmith 2nd Class (AM2) Robert McAuliffe, completed the longest unescorted helicopter flight on record. They flew a Sikorsky HO3S-1G, serial number 51-234, from the Coast Guard Air Station, Elizabeth City, North Carolina, to Coast Guard Air Station Port Angeles, Washington, via San Diego, California, covering a distance of 3,750 miles (6,035 kilometers) in 57.6 flight hours over 11 days.

Lieutenant Graham was the first Coast Guard pilot to fly a helicopter from a ship.¹ On 16 January 1944, he flew a Sikorsky HNS-1, Bu. No. 46445,² from the deck of a British freighter, SS Daghestan, while in convoy from New York to Liverpool. After 30 minutes, he returned to the freighter. He was a pioneer in the use of the helicopter by the Coast Guard and the Navy.

The HO3S (Sikorsky S-51) was a second-generation helicopter, capable of carrying a pilot and up to three passengers. The cabin was built of aluminum with Plexiglas windows. The fuselage was built of plastic-impregnated plywood, and the tail boom was wood monocoque construction.

The main rotor consisted of three fully-articulated blades built of metal spars and plywood ribs and covered with two layers of fabric. (All metal blades soon became available.) The three bladed semi-articulated tail rotor was built of laminated wood. The main rotor turned counter-clockwise, as seen from above. (The advancing blade is on the helicopter’s right.) The tail rotor was mounted on the helicopter’s left side in a pusher configuration. It turned clockwise as seen from the helicopter’s left.

The helicopter’s fuselage was 41 feet, 7.5 inches (12.687 meters). The main rotor had a diameter of 48 feet (14.630 meters) and tail rotor diameter was 8 feet, 5 inches (2.2.565 meters) giving the helicopter an overall length of 57 feet, 1 inch (17.399 meters). It was 13 feet, 1.5 inches (4.001 meters) high. The landing gear tread was 12 feet (3.7 meters).

The S-51 had an empty weight of 4,050 pounds (1,837.05 kilograms) and maximum takeoff weight of 5,500 pounds (2,494.76 kilograms). Fuel capacity was 100 gallons (378.5 liters).

The helicopter was powered by an air-cooled, supercharged, 986.749-cubic-inch-displacement (16.170 liter) Pratt & Whitney R-985 AN-5 (Wasp Jr. T1B4) direct-drive,  nine-cylinder radial engine which was placed vertically in the fuselage behind the crew compartment. This engine had a compression ratio of 6:1 and was rated at 450 horsepower at 2,300 r.p.m., Standard Day at Sea Level. The R-985 AN-5 was 48.00 inches (1.219 meters) long, 46.25 inches (1.175 meters) in diameter and weighed 684 pounds (310.3 kilograms) with a magnesium crankcase.

The S-51 had a maximum speed (Vne) of 107 knots (123.1 miles per hour/198.2 kilometers per hour). Range was 275 miles (442.6 kilometers). The service ceiling was 14,800 feet (4,511 meters). The absolute hover ceiling was 3,000 feet (914.4 meters).

Sikorsky built 220 helicopter of the S-51 series.
