Stinger firing procedure
Firing a Stinger is a rather more complicated procedure that the "point, lock, shoot" usually depicted in media. First, the user removes the front end cap of the LTA, which protects the thin IR window in front of the missile's seeker. The BCU cap is then removed and a BCU is inserted (Stingers are not shipped with BCUs inserted, for safety reasons), then activated by pressing the gripstock's safety and actuator switch forward, outward and downward, then releasing it. The weapon takes 3-5 seconds to warm up after this, during which time a whine can be heard as the internal gyros spin up. The user begins the lock-on procedure by pointing the Stinger's reticle at an empty area of sky, since the launcher uses negative contrast to detect potential targets. The sight is then held on the target until the Stinger generates a lock-on tone: this is delivered through two means, a small but loud speaker mounted on the sight, and a vibrating pad that presses against the gunner's cheek in case they cannot hear the speaker. When the lock has been acquired, the user presses the uncaging switch near the front of the gripstock (which should make the lock-on tone louder), applies lead and superelevation, and then while still pressing the uncaging switch, holds their breath and pulls the trigger. There is a slight delay between pulling the trigger and the missile actually launching.
On launching, the IR window at the front and bursting disc at the rear of the tube are both blown out. The Stinger is ejected from the tube by a small launching motor which is still burning as it exits, which is why the sight includes a plastic panel to protect the gunner's left eye: it is not uncommon for Stinger gunners to wear gas masks for firing exercises to protect them from heat wash and toxic exhaust fumes. The launch motor breaks away from the missile as it exits the tube and hits the ground some distance in front of the launcher. A lanyard connects the launch motor to a shorting plug in the missile's main flight motor arming circuit, and pulls this plug out as it detaches: the missile travels about 29 feet before its first-stage engine ignites. The two stages consist of a main flight motor and sustainer motor which together accelerate the missile to about Mach 2.5. The missile does not begin to manoeuvre until it has travelled 660 feet (200m), meaning it would only be effective against a totally stationary target like a hovering helicopter any closer than this. Stinger typically has a maximum flight time of 15-19 seconds: if it has not hit something before this, the missile will self-destruct. FIM-92C Stinger-RMP has a quoted maximum range of 5 miles (8km).
After firing, the BCU is removed and discarded, the IFF interrogator disconnected, and the IFF antenna stowed: when time permits, the gripstock is detached from the spent LTA. The LTA can be discarded, but is typically destroyed in some expedient manner (this practice comes from US experience with discarded LAWs being packed with explosives and used as boobytraps in Vietnam).
While Stinger is a soft-launch weapon, this is relative to the main flight motor's power and it is certainly no "cold" launch. In combat the backblast danger zone from firing is 50 feet (15m) for personnel and 16 feet (5m) for equipment, and it is dangerous to fire the weapon at elevations greater than 65 degrees due to the backblast potentially injuring the user's legs. It is also dangerous to handle the BCU by anything but the handling ring for 30 minutes after use, as the cartridge heats up to 400 degrees Fahrenheit 3-5 minutes after activation due to the operation of the thermal battery: it must be removed before this time to avoid damage to the gripstock.

Question
Would using this weapon as a conventional rocket launcher work in real life?
- Not really. For a start, from what I can gather you'd need to build a new guidence system if you wanted it to lock on to ground targets. If you just fired the missile regardless, it's pretty thin and doesn't have the biggest warhead in the universe; it'd be a waste of a complicated, expensive weapon to just fire it straight forward. Might as well use a LAW. Vangelis 21:18, 12 February 2011 (UTC)
- Not to mention that it has an HE-Frag warhead, so you'd basically have a big, expensive grenade. Orca1 9904 21:22, 12 February 2011 (UTC)
- As others have said, it's a proximity explosive warhead designed to take down aircraft. Now in the film Navy SEALs they used it as a last ditch weapon against an armored vehicle, but I hope people don't start thinking of it as an anti tank weapon. A total waste of a VERY expensive rocket......MoviePropMaster2008 02:37, 13 February 2011 (UTC)
- Minor correction: IIRC the Stinger is a "hittile" like Rapier that doesn't use a proximity fuze. He's probably thinking of videogames; Metal Gear Solid is the chief offender, where you have to take down a giant walking tank by firing Stingers at it. Vangelis 09:28, 13 February 2011 (UTC)
Page rename?
Should this be moved to "FIM-92 Stinger", as the FIM-92A is just the first of 5 variants of the missile, with the outward appearance of the launchers being identical. Also, does anyone know what the "M" designation for the launcher itself is, like how the launcher for the FIM-43 Redeye is the M41A1? --commando552 04:27, 27 July 2012 (CDT)
Other Variants
Does anyone know the differences of other designated Stinger Variants. Probably for different launch platforms, I'm not sure
- By designation do you mean the difference between the FIM-92A and the other letter designations such as FIM-92B? If so, I don't think there is any external difference on the launcher itself, the only difference is on the missile, with improved warheads, motors, seekers and software. Bear in mind that the designation of FIM-92A (or whatever letter up to G I think) is for the missile itself, the launcher has a different designation. So for example even though there is not launcher resembling what you would think of as a Stinger MANPAD on vehicles like the Avenger or Linebacker, you would still say that they are armed with FIM-92Bs as this is the missile itself. I don't know what the designation is for the MANPAD launcher system, but similarly for its predecessor the Redeye the missile is the FIM-43, whilst the launcher itself is designated as the M41A1. --commando552 (talk) 08:09, 7 January 2013 (EST)
