3M6 Shmel

3M6Shmel/ AT-1 Snapper anti-tank missiles.

The3M6Shmel(Russian:3М6 «Шмель»;English:bumblebee) is anMCLOSwire-guidedanti-tank missileof theSoviet Union.ItsGRAUdesignation is "3M6" and itsNATO reporting nameisAT-1 Snapper.

Too large to be manportable, it was typically deployed from specialised vehicles or helicopters. The missile was intended to supplement traditional anti-tank weapons, like the100 mm anti-tank gunwhose accuracy beyond 1,500 m is poor. The missile's accuracy in contrast remained high as far as its maximum range of 2,000 m.

However, the system's bulk, slow speed and poor combat accuracy drove development of laterSACLOSsystems, like the9M113 Konkurs.

Development[edit]

The3M6Shmelbegan development through Decree No. 7 on May 27, 1957.[1]Development would be spread across several bureaus and research institutes, with the missile complex and rocket being designed bySKB-4,[2]led byBoris Shavyrinunder the leadership of the to-be famousSergey Nepobedimy,[3]being based on theNord AviationSS.10.[2][4]Teams fromTsNII-113[ru],[5][6]led by Zinovy Moiseevich Persits, would handle the design of thecontrol system.Meanwhile, thechargefor thesolid-propellantrocket enginewould be designed byNII-125,and theHEATwarheadbyNII-6.[3]

Development of the missile proceeded rapidly, with the first unguided flights in April 1958 followed by controlled flights in June and July 1958, where testing showed theprobability of a hitto be anywhere from 75—90%, depending on the range.[7]However,Soviet Armyfield exercises showed that hit rates could decrease to as low as 25% due to the complexity of theguidance system.[8]

Reveal and Western reaction[edit]

The system would enter service by August 1st, 1960.[9]Later, parade 2P27 vehicles sporting four 2K16 launchers on May 1st, 1962 were noted byWesternobservers in parade formation, just before the 1962Moscow Victory Day Parade.[10]The weapon would later be described in theUS ArmyjournalMilitary Reviewas being 'about the same size' and having 'approximately the same range' as the FrenchSS.11,later overestimating its range to be from 500 to 3,000 metres.[11]

History[edit]

2P26 in Batey ha-Osef Museum, Israel.
Polish 2P27

There were two ground-based platforms for the missile

  • 2P26Based on the unarmoredGAZ-69light truck - with four backward pointing launch rails. The control station can be deployed up to 30 m away from the launcher vehicle. It entered service in 1960
  • 2P27Based on the armoredBRDM-1- with three pop up launch rails protected by an armored cover. It entered service in 1964.

These vehicles were deployed in anti-tank batteries attached to motor rifleregiments.Each battery has threeplatoons,each with three launch vehicles and a single command BRDM.

While a few were used by Egyptian forces during the 1967Six-Day Warand from 1969 in theWar of Attrition,only one tank loss was attributed to the system. The system's hit probability is estimated to have been 25% in combat[citation needed].

The system was also used by theCypriot National Guardduring the1974 Turkish invasion of Cyprusin a man-portable version. Several dozen shots were fired in action during a number of July and August engagements in the conflict, with low effectiveness.

North Koreabegan producing a reverse-engineered version of the missile in 1975.

Description[edit]

The missile is guided to the target by means of a joystick, which requires some skill on the part of the operator. The operator's adjustments are transmitted to the missile via a thin wire that trails behind the missile.

The missile is steered by an unconventional arrangement of vibrating spoilers.

As stated before, MCLOS requires considerable skill on the part of the operator. The system's effectiveness in combat drove the development of missiles based on the easier to use SACLOS system.

One problem with the missile is the amount of time it takes to reach maximum range—around 20 seconds—giving the intended target time to take action, either by retreating behind an obstacle, laying down a smoke screen or firing on the operator. Also, the large size of the missile means that only a few rounds can be carried; theBRDM-1vehicle can only carry three missiles.
