With the addition of a new tail section that contains an inertial navigational system and a global positioning system guidance control unit, JDAM improves the accuracy of unguided, general purpose bombs in any weather condition. JDAM is a joint U.S. Air …

The Joint Direct Attack Munition (JDAM) is a guidance kit that converts unguided bombs, or "dumb bombs", into all-weather precision-guided munitions (PGMs). JDAM-equipped bombs are guided by an integrated inertial guidance system coupled to a Global Positioning System (GPS) receiver, giving them a published range of up to 15 nautical miles (28 km).

GBU-31炸弹口径为2000磅（约908千克），弹体直径为460毫米（Mk-84）或370毫米（BLU-109/B），装药量约为429千克，采用触发或非触发引信。 另一种通用爆破型炸弹是GBU-32，该型号口径为1000磅（454千克），全弹重500千克，弹体直径为356毫米（MK-83）。

The GBU-31(v)3 is a “bunker-buster” weapon, which uses a specially built BLU-109 bomb body of the 2,000-lb class, and unique fuse settings to allow the bomb to penetrate heavily fortified structures such as multi-story buildings, caves, and bunkers.

Developed by Boeing for the U.S. Air Force and U.S. Navy, the Joint Direct Attack Munition (JDAM) guidance tail kit converts unguided, free-fall "dumb" bombs into accurate, all-weather "smart" Guided Bomb Units (GBU). These bombs cost much less than laser,

The Joint Direct Attack Munition (JDAM) GBU-31 is a tailkit under development to meet both USAF and Navy needs, with the Air Force as the lead service. The program will produce a weapon with high accuracy, all-weather, autonomous, conventional bombing capability.

2024年9月30日 · The GBU-31(V)3/B can be released from altitudes up to 15,240 meters at speeds ranging from Mach 0.6 to Mach 1.2. It undergoes several flight phases: separation with fins locked, optimal guidance using GPS and INS data, and impact, where it adjusts its angle for optimal penetration before detonation.

Mission The Joint Direct Attack Munition is a guidance tail kit that converts existing unguided free-fall bombs into accurate, adverse weather "smart" munitions. With the addition of a new tail section that contains an inertial navigational system and a,

gbu-31/32/38 jdam Joint Direct Attack Munition is a GPS/INS-guided, autonomous, all-weather surface attack weapon. The joint USAF-Navy program upgrades the existing inventory of general-purpose bombs by adding a GPS/INS guidance kit for accurate all-weather attack from medium/high altitudes.

JDAM is a family of guided air-to-surface weapons that is comprised of the GBU-31(V)2/B, GBU-31(V)4/B, GBU-32(V)2/B, and GBU-35(V)1/B for the United States Navy (USN) and United States Marine ...
