In 1995 work began on using the Tu-16 as the carrier for the K-10s(AS-2 Kipper) cruise missile for the Soviet Naval Air Force for use in an anti-shipping role. The missile's guidance system was added as an onboard system, with the missile mounted semi submerged under the fuselage on the centerline in the bomb bay area. The glazed nose was replaced by broad flat radome housing antenna for the YeN targeting radar. A missile top-off fuel tank was housed in the bomb bay, along with a small pressure cabin for the YeN radar operator. The Tu-16K-10 prototype was finished in 1958 and series production started in 1959. Deployment into the Soviet Naval Air Force began in October 1961. A total of about 220 were built, many of which were subsequently converted to Elint/EW platforms.
