1 July 1960: A United States Air Force Boeing RB-47H-1-BW Stratojet, 53-4281, assigned to the 38th Strategic Reconnaissance Squadron, 55th Strategic Reconnaissance Wing, based at Forbes Air Force Base, Kansas, was conducting an electronic reconnaissance mission in international airspace over the Barents Sea, north of the city of Murmansk, in the northwest part of the Soviet Union. The RB-47 had departed from RAF Brize-Norton, in Oxfordshire, west northwest of London, England. The mission was code-named BOSTON CASPER.

On board the RB-47 were a crew of six: Major Willard George Palm, aircraft commander;  Captain Freeman Bruce Olmstead, co-pilot/gunner; Captain John McKone, navigator/photographer; and three electronic intelligence officers (known as “Ravens”): Major Eugene E. Posa, Captain Dean Bowen Phillips, and Captain Oscar Lee Goforth.

Captain Vasily Ambrosievich Polyakov

At Monchegorsk Air Base on the Kola Pennisula, Captain Vasily Ambrosievich Polyakov, 174th Guards Red Banner Fighter Aviation Regiment (Boris Feofontovich Safonov) was on strip-alert in the cockpit of his Mikoyan-Gurevich MiG-19 interceptor. Captain Polyakov was interviewed in 1995 and described being “scrambled” to intercept the American reconnaissance plane. Vectored by radar controllers, he flew north-northwest until he located the B-47.

Polyakov said that he waggled his wings at the bomber—an international signal for the intercepted aircraft to follow the fighter. He saw no response. Controllers then ordered him to shoot down the American airplane.

Captain Polyakov made a firing pass and fired two bursts with the MiG’s three 30 mm autocannon, for a total of 111 rounds expended. He saw the B-47 roll inverted and disappear into the clouds below. He did not see any parachutes, nor did he observe the aircraft crash. Polyakov then returned to his base.

Captain Olmstead later reported that he had returned fire with the two 20 mm autocannon in the B-47’s tail, expending “two-thirds of my ammunition,” or about 462 rounds. The MiG’s cannon fire knocked out two of the three engines on the left wing. The bomber entered a spin but Palm and Olmstead were able to recover. After Polyakov’s second firing pass, though, the crew ejected. Now derelict, 53-4821 continued to fly to the northeast for approximately 200 miles (322 kilometers).

A Russian source indicated that this was the first air combat victory for the MiG-19.

A National Security Agency SECRET SPOKE document states “After the shootdown, probably all six crewmen bailed out, but only two men, the co-pilot and navigator, survived the splashdown into the icy waters of the Barents.” ¹

After six hours in the freezing water, Captains Olmstead and McKone were rescued. McKone had a crushed vertebra as a result of the ejection. The body of Major Posa was also recovered. Major Palm’s body was recovered on 4 July. Captain Goforth and Captain Phillips were never found and were presumed to have died.

Olmstead and McKone were imprisoned in the notorious Lubyanka Prison by the Soviet security service, and interrogated extensively. It wasn’t until 15 July that McKone received medical treatment for his broken back. He would spend the next 97 weeks in traction.

On 25 July, Major Palm’s body was returned to the United States for burial. Major Posa’s was sent to Severomorsk, then on to Moscow. Eventually his remains were buried in an unknown cemetery. The Defense POW/MIA Accounting Agency (DPAA) lists his status as unknown, non-recoverable.

Designed by Boeing, the Stratojet was a high-subsonic speed strategic bomber and reconnaissance aircraft, in service from 1951 until 1977. When it was introduced, the B-47 could fly higher and faster than jet fighters of the time, and it was also highly maneuverable.

The RB-47H Stratojet (Boeing Model 450-172-52) was an electronics reconnaissance variant of the B-47E strategic bomber, designed to detect, identify and locate electronic signals. It was flown by a two pilots in a tandem cockpit. A navigator was located at a station in the nose. Three electronics intelligence officers were in a reconnaissance compartment. The RB-47H Stratojet is 108.7 feet (33.132 meters) long with a wingspan of 116.3 feet (35.448 meters), and an overall height of 28.0 feet (8.534 meters). The wings are shoulder-mounted with an angle of incidence of 2° 45′, and their leading edges are swept aft to 36° 37′. There is no dihedral, but the wings are very flexible and move considerably during flight. They have a total area of 1,428 square feet (132.67 square meters). The RB-47H had an empty weight of 89,230 pounds (40,474 kilograms)—nearly 10,000 pounds (4,536 kilograms) heavier than the B-47E bomber. Its maximum takeoff weight was 218,728 pounds (99,213 kilograms). Once airborne, the maximum weight could be increased to 221,000 pounds (100,244 kilograms) with inflight refueling.

The RB-47H was powered by six General Electric J47-GE-25 turbojet engines in four nacelles mounted on pylons below the wings. This engine has a 12-stage axial-flow compressor, eight combustion chambers, and single-stage turbine. The -25 has a normal power rating of 5,320 pounds of thrust (23.665 kilonewtons) at 7,630 r.p.m., at Sea Level; Military Power, 5,670 pounds (25.221 kilonewtons) at 7,800 r.p.m.; and Maximum Power, 7,200 pounds (32.027 kilonewtons) at 7,950 r.p.m. with water/alcohol injection. (As of July 1964, there were no time limits on Military or Maximum Power.) The J47-GE-25 has a maximum diameter of 3 feet, 1 inch (0.940 meters) and length of 12 feet, 0 inches (3.658 meters) and weighs 2,653 pounds (1,203 kilograms)

The RB-47H had a basic speed of 419 knots (482 miles per hour/776 kilometers per hour) at 35,000 feet (10,668 meters); combat speed of 460 knots (529 miles per hour/852 kilometers per hour) at 37,200 feet (11,339 meters), and maximum speed of 516 knots (594 miles per hour/956 kilometers per hour) at 15,000 feet (4,572 meters). The service ceiling was 45,000 feet (13,716 meters).

The combat radius of the RB-47H was 1,520 nautical miles (1,749 statute miles/2,815 kilometers. Ferry range with 18,402 gallons (69,659 liters) of fuel was 3,403 nautical miles (3,916 miles/6,302 kilometers).

For defense, the RB-47H was armed with two M24A1 20 mm autocannons with 350 rounds of ammunition per gun. The remotely-operated tail turret was controlled by a radar-computing A-5 fire control system, operated by the co-pilot, whose seat could swivel to allow him to face rearward.

The forward bomb bay was modified to incorporate a pressurized compartment for the electronic intelligence operators’ stations.

A total of 2,032 B-47s were built by a consortium of aircraft manufacturers: Boeing Airplane Company, Wichita, Kansas; Douglas Aircraft Company, Tulsa, Oklahoma; Lockheed Aircraft Company, Marietta, Georgia. 35 of these were the RB-47H variant, produced by Boeing Wichita. Three of these were further modified to ERB-47Hs.

The Stratojet is one of the most influential aircraft designs of all time and its legacy can be seen in almost every jet airliner built since the 1950s: the swept wing with engines suspended below and ahead on pylons. The B-47 served the United States Air Force from 1951 to 1977. From the first flight of the Boeing XB-47 Stratojet prototype, 17 December 1947, to the final flight of B-47E 52-166, was 38 years, 6 months, 1 day.
