18-786: As NCSIST's previous experience with anti-ship missile development was limited to experimentally fitting warheads onto MQM-33B drones, the decision was made to base the weapon on the Israeli Gabriel Mk I with necessary modifications added in order to remain competitive against the SY-1 missile, making it essentially a Taiwanese interpretation of the Gabriel Mk II (and since the Republic of China Navy did also import several sets of Gabriel Mk II system to rehabilitate three of their Allen M. Sumner class destroyers, they also stipulated

36-625: A radar signature of a larger aircraft. The radar reflectors (Luneburg lens) wasn't used by the US Navy as the air search radar interfered with the control signals. Thus the air search radar was not used. Launch was by RATO booster or bungee catapult, and recovery by parachute. A variant of the BTT designated the RP-71 , also known as the SD-1 Observer and later redesignated MQM-57 Falconer ,

54-522: A little more than a half-hour, making it of limited use, about 1,500 Falconers were built and the type was used internationally with several different military forces, remaining in service into the 1970s. Over 76,000 BTT targets were built in all – more than any other type of aircraft – and the type was used by at least 18 nations. Data from Jane's All The World's Aircraft 1966–67. General characteristics Performance McCulloch Motors Corporation McCulloch Motors Corporation

72-583: A major improvement over existing technology, and it did not go into production. Radioplane was bought out by Northrop in 1952 to become the Northrop Ventura Division, though it appears that the "Radioplane" name lingered on for a while. In 1963, when the US military adopted a standardized designation system, the surviving US Army BTT variants became MQM-33s and the KD2R-1, the only member of

90-617: A narrow focus on lawn and garden equipment. By 1978, Charles Hurwitz had 13% holdings in the company. Black and Decker bought McCulloch on 4 October 1974, and sold the company to a private group in November 1984. In January 1999, the company filed for Chapter 11 bankruptcy and sold its European division to Husqvarna AB . In October 1999, its North American operation was acquired by the Taiwanese company Jenn Feng Industrial Co. Jenn Feng added electric power tools and pressure washers to

108-586: Is an American manufacturer of chainsaws and other outdoor power tools . The company was founded in Milwaukee , Wisconsin, in 1943 by Robert Paxton McCulloch as a manufacturer of small two-stroke gasoline engines and introduced its first chainsaw in 1948, the Model 5-49. McCulloch and its brand are owned by Husqvarna . McCulloch moved its operation to California in 1946. In the 1950s, McCulloch manufactured target drone engines, which were sold to RadioPlane in

126-572: The 1970s. These McCulloch 4318 small four cylinder horizontally opposed two-stroke engines were also popular for use in various small autogyros , such as the Bensen B-8 M and Wallis WA-116 . McCulloch also started Paxton Automotive , manufacturing McCulloch-labeled superchargers like the one fitted to the Kaiser Manhattan, the 1957 Studebaker Golden Hawk , and Ford Thunderbird . In 1959, they produced their first kart engine,

144-686: The HF-I to be made interchangeable with the Israeli-made ordnance). The system uses the Taiwanese CS/SPG-21A as a target acquisition and fire control radar. The CS/SPG-21A reportedly has a range of 37 km which was later upgraded to 46 km. The Hsiung Feng I was officially a reverse-engineered version of Gabriel Mk.2 antiship missile, although Israel is believed to have cooperated with Taiwan. Sun Yat-sen Institute and National Chung-Shan Institute of Science and Technology redesigned

162-573: The Hsiung Feng II on larger patrol craft and in coastal batteries, the HF-1 is being phased out of service (along with Hai Ou class FACs). The last ship to carry the missile converted to the HF-2 in early 2013. The missiles were sent back to NCSIST for decommissioning. The IA variant was created to address deficiencies with the radar radio frequency altimeter, cooling system, and the rocket motor of

180-574: The McCulloch MC-10, an adapted chainsaw two-stroke engine. Bill Van Tichelt of VanTech Engineering designed and produced one of the first specialized and most successful intake manifolds for the McCulloch kart engine, along with mufflers, conversion kits, throttle linkages, air stacks and bottom slopers. In 1964, McCulloch founded Lake Havasu City , Arizona , with a factory and housing for its workers. The company founder Robert McCulloch

198-579: The family still in Navy service, became the MQM-36 Shelduck . The MQM-36 was the most evolved of the BTT family, but retained the same general configuration as the other members. It was larger and more sophisticated than the first-generation OQ-2A series, and was powered by a more powerful flat-four four-stroke McCulloch piston engine with 72 hp (54 kW). The MQM-36 carried Luneburg lens radar enhancement devices in its wingtips that generated

216-479: The late 1940s, evolving through a series of refinements with the US Army designations of OQ-19A through OQ-19D , and the US Navy name of Quail with designated KD2R . Early models had a metal fuselage and wooden wings, but production standardized on an all-metal aircraft. Radioplane developed an experimental XQ-10 variant that was mostly made of plastic, but although evaluations went well, it wasn't considered

234-488: The missile to include Taiwanese components. First test-fire of Hsiung Feng I was done in 1977. Initial production started in 1979. HF-I design flaws with the radar radio frequency altimeter, cooling system, and the rocket motor undermined the missile's effectiveness. Taiwan redesigned the missile to create the Hsiung Feng IA (HF-1A), which went into production in 1981. The missile was in service until 2012. Prior to

252-611: The missile. The redesigned missile was designated HF-1A and entered production in 1981. Radioplane BTT The Radioplane BTT , known as RP-71 by the company, as WS-426/2 by the United States Navy , and as WS-462/2 by the US Air Force , is a family of target drones produced by the Radioplane Company (later a division of Northrop ). In the post-World War II period, Radioplane followed up

270-632: The service entry of the Hsiung Feng II missile, it was the primary anti-ship weapon on all of the ROC Navy's frontline surface combatants, including the majority of the service's Gearing class and Allen M. Sumner class destroyers. It is currently deployed on the ROCN's littoral combatants, most notably the Hai Ou class missile boats , as well as some land based facilities. Due to it being superseded by

288-571: The success of the OQ-2 target drone with another very successful series of piston-powered target drones, what would become known as the Basic Training Target (BTT) family (the BTT designation wasn't created until the 1980s, but is used here as a convenient way to resolve the tangle of designations). The BTTs remained in service for the rest of the 20th century. The BTT family began life in

306-469: Was built for battlefield reconnaissance, with first flight in 1955. The Falconer was similar in appearance to the Shelduck, but had a slightly longer and stockier fuselage. It had an autopilot system with radio-control backup, and could carry cameras, as well as illumination flares for night reconnaissance. Equipment was loaded through a hump in the back between the wings. Although it only had an endurance of

324-619: Was involved in buying the London Bridge at auction in the 1960s. It was then reassembled in Lake Havasu City and opened in 1971. In 1967, McCulloch discontinued its line of outboard boat engines which it began after the 1956 purchase of Scott-Atwater Manufacturing Company of Minneapolis, Minnesota - the manufacturer of Scott-Atwater outboard boat engines. In the 1970s their range was expanded to add generators, hedge trimmers, string trimmers, and leaf blowers , but started
