In 1979, with nearly 20 years’ experience of building Mil-designed hclicoptors behind it, Poland’s PZL Swidnik flew the first prototype of a new design designated W-3 and named Sok6l, or ’Falcon’. There was a long series of tethered tests and extensive design changes before the second prototypo flew in May 1982, and it was another three years before production began. Since then, PZL has developed several specialised variants for military and civil applications.
Developed for tho USAF from tho HRP tandem-rotor designs, the H-21 made Its mark with tho US Army, which named its the Shawnee. After missing the Korean War by just a year, the twin-rotor H-21 Workhorse (its USAF name) entered service with Army aviation units In the 1950s and went to war briefly In Vietnam in the 1960s, the swansong of its career. A few oxamples served with foreign forces, mainly under the Military Assistance Program.
Operated by tho Bth and 57th Transportation Companies, and armed with Browning machino-guns. tho CH-21C served (or just two years.
▼ Difficult start
A military training variant has undergone flight testing with the Soviot armed forces as a possible replacement for the Mi – UMi-2.
