M47 Dragon ATGM with SU-36/P daysight - 140mm

The M47 Dragon is a crew-served, man-portable wire-guided SACLOS (semi-active command line of sight) missile launcher introduced in 1975 and used by the US military: while many remain in US Army and USMC stockpiles, it was officially withdrawn from service in 2001, having been replaced by the FGM-148 Javelin. It was developed under the name FGM-77 by Raytheon and manufactured by Raytheon and McDonnell Douglas, replacing the M67 recoilless rifle.

The Dragon uses a similar guidance system to other period systems like the BGM-71 TOW, with the sight tracking a thermal beacon on the missile's tail to make course corrections and issuing commands to the missile via wires. It uses a similar soft-launch system with a smaller rocket engine propelling it clear of the launch tube, with a rather strange twist: instead of the missile achieving full flight speed using a main rocket engine and then gliding to the target using wings and steering fins, Dragon's missile lacks control surfaces entirely, with only small stabilising fins at the rear, and has no large second stage engine. It instead features thirty pairs of small rocket thrusters along the midsection which fire to both keep it in the air and correct its flight path, creating distinctive popping sounds at intervals of half a second to a second as it flies depending on how much it is required to manoeuvre. For safety, the warhead does not arm until the missile has travelled 65 metres: maximum range is 1,000 metres, increased to 1,500 with the improved Super Dragon missile in 1990.

Like its successor the Javelin, the Dragon is a two-part system with a disposable encased missile and a re-usable sighting unit which is attached to the round prior to use. A tripod mount and vehicle mount were also available for a more stable firing platform. The standard missile uses a single-stage HEAT warhead rated as able to penetrate 8 feet of compacted earth, 4 feet of reinforced concrete, or 13 inches of rolled homogeneous steel. The 1985 Dragon II and 1990 Super Dragon both improved on this performance, with the latter said to be capable of penetrating 18 inches of RHA.

Being a shoulder-fired system, Dragon had the problem that while there was no real recoil on firing, the soldier would suddenly be relieved of the weight of the 20-pound missile, which could throw the launcher violently off-target and cause the missile to ground itself: for this reason, Dragon was only supposed to be used with its supporting bipod deployed. It was not a well-liked weapon due to being difficult to use (like TOW, there is a short delay between pulling the trigger and the missile firing, which was much more problematic for Dragon, moving the sight too quickly will cause the missile to ground itself, and it has a fearsome backblast with a "danger zone" almost a hundred feet long to the rear in a 90-degree arc), a tendency for the control wires to break, thruster failures, and the regular thruster firing making it impossible to not tell when one had been fired. A report by the US Army found Dragon's hit rate under combat conditions to be a dismal 20%. Dragon's single-stage HEAT warhead was quickly rendered obsolete by developments in reactive armour, and by the time it was actually employed in full-scale combat in the Gulf War, it was considered a weapon of last resort.

An expended launch tube is relatively easy to get hold of since many jurisdictions treat them in the same way as spent rounds of ammunition: therefore, live-action appearances are likely to only be the fibreglass launch tube rigged with a pyro charge to simulate firing, and with the sighting unit (which a Dragon missile cannot be fired without, among other things because the weapon's trigger is on the right side of it) either totally absent or replaced with a prop replica.
