The Ilyushin Il-28 is a jet bomber aircraft that was originally manufactured for the Soviet Air Force. It was the USSR's first such aircraft to enter large-scale production. The NATO reporting name for the type is Beagle for the bomber, Il-28R reconnaissance version, and Il-28T torpedo-bomber, and Mascot for the Il-28U trainer version. It was also licence-built in China as the Harbin H-5. Total production in the USSR was 6316 aircraft, and over 319 H-5s were built. Only 187 examples of the HJ-5 training variant were manufactured. In the 1990s hundreds remained in service with various air forces over 40 years after the Il-28 first appeared.

Design and development

The aircraft is conventional in layout, with high, unswept wings carrying large engine nacelles beneath them. The bombardier is accommodated in the glazed nose, and the other end of the fuselage carries a turret with two 23 mm cannons. These features make it resemble the World War II medium bombers that preceded it, but the swept tail surfaces and the pilot's bubble canopy and ejector seat were more similar to other aircraft of its own era, making it a blend of old and new features.

Operational history

The Il-28 was widely exported, serving in the air arms of some 20 nations ranging from the Warsaw Pact to various Middle-Eastern and African air forces. Egypt was an early customer, and targeting Egyptian Il-28s on the ground was a priority for the Israeli Air Force during the Suez Crisis, Six Day War, and Yom Kippur War. The Soviet Union was in the process of providing the type for local assembly in Cuba when this was halted by the Cuban Missile Crisis, after which Nikita Khrushchev agreed to remove them. The type also saw limited use in Vietnam and with the Afghan forces in Afghanistan. Four ex-Egyptian and two ex-Soviet Il-28s (all with Egyptian crews) were operated by the Nigerian Air Force in the Biafra Wars. Yemeni Il-28s took part in the civil war in that country. Finland also had four examples of this type delivered between 1961 and 1966. They remained in service until the 1980s.

The Soviet Union withdrew the type in the 1980s, while the last Soviet-built examples were still flying in Egypt into the 1990s. Chinese-built Il-28s designated H-5 and built by HAMC were also flying in the 1990s with several hundred in China itself, and a smaller number in North Korea and Romania. The three main Chinese versions are the H-5 bomber, followed by the HJ-5 trainer, and the H-5R (HZ-5) long range (in comparison to the reconnaissance version of Shenyang J-6) reconnaissance aircraft, and later, the HD-5 ECM/ESM version. The latter two types have been phased out.

The type is known to still be in active frontline service the North Korean Air Force in respectable numbers, although little is known as to whether they are a mix of survivors from the batch of 24 Soviet manufactured aircraft delivered in the 1960s and some of the newer Chinese built H-5 variant, or are solely H-5s.

First Il-28 in the West

On 11 November 1965, Li Xianbin (李显斌), a PLAAF captain of an Ilyushin Il-28 of the 8th division defected by flying his bomber numbered 0195 from Jianqiao (笕桥) air base in Hangzhou to Chiang Kai-shek International Airport, and this was the first fully operational Il-28 in western hands. The radio operator / tail gunner Lian Baosheng (廉保生) was found dead at the scene and the navigator Li Caiwang (李才旺) was captured alive after a failed suicide attempt. Both survivors were honored and rewarded positions in the Republic of China Air Force. Li Xianbin (李显斌) was rewarded 2,000 taels (approximately 70 kg) of gold, while Li Caiwang (李才旺) was rewarded 1,000 taels (approximately 35 kg) of gold. Since Lian Baosheng (廉保生) was dead, his reward of 1,000 taels (approximately 35 kg) of gold was divided evenly among Li Xianbin (李显斌) and Li Caiwang (李才旺).
