Cold War / Modern Era

1945 – 1991

Overview

The Cold War was defined by the paradox of nuclear deterrence: two superpowers capable of destroying each other — and potentially all human civilization — chose instead to compete through proxy wars, arms races, and technological competition. The direct confrontation that never came shaped every weapon system developed in this period.

Both the United States and Soviet Union poured vast resources into weapons development. The results included the assault rifle (which armed most of the world's militaries and insurgencies), precision-guided munitions, nuclear submarines, intercontinental ballistic missiles, jet aviation, and the first guided anti-tank and anti-aircraft systems available to infantry.

The Assault Rifle Era

The assault rifle — a selective-fire weapon firing an intermediate cartridge from a detachable magazine — became the universal infantry weapon of the Cold War period.

Soviet / Warsaw Pact

• AK-47 (Avtomat Kalashnikova 1947) — Designed by Mikhail Kalashnikov; 7.62×39mm; 30-round magazine; gas-operated rotating bolt; perhaps the most influential weapon design in history; estimated 100+ million produced; simple, robust, and effective in adverse conditions
• AKM — Modernized AK-47; stamped receiver; lighter; adopted 1959
• AK-74 — 5.45×39mm intermediate cartridge; adopted 1974; reduced recoil; still standard Russian service rifle
• RPK — AK-based light machine gun; 40 or 75-round magazine; squad automatic weapon
• PKM — 7.62×54mmR general-purpose machine gun; belt-fed; still widely used globally

American / NATO

• M14 — 7.62×51mm NATO; 20-round magazine; semi-automatic with selective fire; replaced by the M16
• M16 (AR-15) — 5.56×45mm; designed by Eugene Stoner; adopted 1964; initial reliability problems in Vietnam; subsequently refined; still in service as M16A4
• M4 Carbine — Shortened M16; 14.5" barrel; the current US standard infantry rifle
• M249 SAW — 5.56mm belt-fed light machine gun; squad automatic weapon
• M60 machine gun — 7.62mm GPMG; replaced in most roles by the M240

Handguns

• Soviet Makarov PM — 9×18mm; simple, reliable; Soviet and Warsaw Pact standard sidearm
• American M1911A1 — .45 ACP; continued in US service until 1985
• Beretta M9 (92FS) — 9mm; 15-round magazine; replaced the M1911 in US service 1985; NATO standard
• Glock 17 — Austrian polymer-framed 9mm; adopted by many NATO and civilian agencies; transformed handgun design

Sniper Rifles

• Soviet SVD Dragunov — 7.62×54mmR; 10-round magazine; designated marksman rifle; widely exported
• American M24 SWS — Remington 700 action in a precision chassis; 7.62×51mm
• Barrett M82 — .50 BMG semi-automatic anti-materiel rifle; can engage light vehicles and equipment at over a kilometer

Anti-Tank Weapons

Guided Missiles

• Soviet 9M14 Malyutka (AT-3 Sagger) — Wire-guided ATGM; used with devastating effect in the 1973 Yom Kippur War
• American BGM-71 TOW — Wire-guided heavy ATGM; vehicle and helicopter mounted; still in use
• American FGM-77 Dragon — Portable infantry ATGM
• FGM-148 Javelin — Fire-and-forget infrared-guided ATGM; "top attack" mode strikes tank roof armor

Recoilless Weapons

• RPG-7 — Soviet rocket-propelled grenade; introduced 1961; perhaps the most widely used anti-tank weapon in history; still in production and combat use worldwide
• American M72 LAW — Single-shot disposable rocket launcher; 66mm; replaced the bazooka

Air Defense

• Soviet SA-7 Grail (9K32 Strela) — First practical MANPADS (man-portable air defense system); shoulder-fired heat-seeking missile
• American FIM-92 Stinger — Improved MANPADS; infrared/UV guidance; used by Afghan Mujahideen against Soviet helicopters with significant effect

Nuclear Weapons

Both superpowers developed thermonuclear weapons (hydrogen bombs) orders of magnitude more powerful than the Hiroshima bomb, along with delivery systems including:

• ICBMs — Intercontinental ballistic missiles capable of reaching any point on Earth in 30 minutes
• SLBMs — Submarine-launched ballistic missiles; virtually invulnerable second-strike weapons
• Strategic bombers — B-52 Stratofortress (US), Tu-95 Bear (Soviet)

The doctrine of Mutually Assured Destruction (MAD) — that a nuclear first strike would guarantee a devastating response — maintained an uneasy peace between the superpowers.

Precision-Guided Munitions

The Vietnam War and subsequent conflicts drove development of precision weapons:

• Laser-guided bombs (LGBs) — First used in Vietnam; dramatically improved strike accuracy
• AGM-65 Maverick — Air-to-ground missile; TV or infrared guided; effective against armor
• Cruise missiles — BGM-109 Tomahawk; terrain-following guidance; accurate to meters at ranges exceeding 1,500 km
