The 155mm M898 Sense and Destroy Armor Munition (SADARM) is designed for top attack of armor by indirect fire. The primary intended use of SADARM is as a counter-battery system. It combines millimeter wave, infrared and signal processing technologies. Each round contains two payload sub-munition packages. The sub-munitions are ejected from the projectile base by expulsion charges. Once clear of the projectile body, onboard sensors search the ground underneath for targets. Once a target is acquired, the sensor will determine the center of the target and the explosive will penetrate the armor vehicle's relatively vulnerable top. Maximum lethal range is approximately 150 meters. The SADARM has demonstrated the ability in tests to destroy two armor vehicles with one projectile.

SADARM (Sense and Destroy Armor) is a "smart" artillery submunition designed for precision engagement of self-propelled howitzers as well as other lightly armored vehicles. By destroying the enemy's self-propelled counterfire capability, SADARM contributes to full-dimensional protection. Denying the enemy's use of self-propelled howitzers better enables friendly forces to move at will and dominate maneuver. The is the basic developmental projectile, and the XM982 - Similiar to the M483A1 with the addition of a rocket motor to further increase the effective range, and with options to increase delivery accuracy.

SADARM is designed to attack and kill lightly armored vehicles. SADARM is dispensed from a 155 millimeter (mm) howitzer round. Each howitzer round delivers two submunitions. Once dispensed, the submunition deploys a parachute-like deceleration device. At a predetermined distance from the ground, the submunition ejects the deceleration device and deploys another device to stabilize and rotate the submunition. As the submunition falls and rotates, it searches the ground with a millimeter wave sensor and an infrared sensor array. Using the two sensors and detection logic, the submunition is designed to detect countermeasured targets in a variety of climates. If the sensor detects a target, the submunition fires an explosively formed penetrator (EFP) at the target. If no target is detected the submunition is designed to self-destruct.

The Army is pursuing a SADARM product improvement (PI) as part of a cost reduction program. The PI will increase SADARM's effectiveness by increasing the detection area and potentially using a new EFP design. Several EFP designs are being considered. The new EFP should increase effectiveness against self-propelled howitzers as well as other targets. The PI will be cut into the current production line. According to the current strategy, the SADARM PI will make up at least 90 percent of the total SADARM buy.

SADARM is currently in low-rate production. After technical tests in June and July 1993, SADARM testing was suspended due to poor performance. The Army conducted an extensive failure analysis and program review. In April 1994, 13 projectiles (26 submunitions) scored 11 hits at a range of approximately 15 kilometers. However, there were still problems at the longest ranges as well as submunition mid-air collision problems.

The Army restructured the program to allow a limited low rate production. The low-rate production supported additional tests of the system. Countermeasure and non-desert tests were also added to the program, and the operational test was expanded as a final confirmation prior to entering full-rate production.

Based on the test results and the restructured program, the defense acquisition board (DAB) allowed the program to enter low rate production in March 1995. The DAB delegated the full rate production decision to the Army contingent on achieving an exit criterion.

Early in 1996, the Army began the first tests of the low-rate production articles. In March and April 1996, the Army conducted tests at Yuma Proving Ground to confirm fixes for the collision problems. There were 8 hits with 9 rounds (18 submunitions) fired at 18 km, close to the longest range. This exceeded the exit criterion for the test and no collisions were observed.

The M898 SADARM is currently in production.



Berhubung sini rame bener ngomongin si Tenky MBT, ane dolan2 eh nyasar ke munisi ginian. Jujur gw baru ngeh keberadaan ni barang pake terjun payung. Apa ini pengembangan dari pelor APFSDS yang ngejar penetrasi?, Denger2 beberapa APFSDS diprotes karena bahannye Depleted Uranium (DU) ngrusak lingkungan ama kesehatan prajurit baik lawan dan kawan itu?. makanya bikin ni sadarm nusbol tengki dari atas yang notabene titik lemah armor. Ade yang tau kelanjutan munisi ini dan pergelarannya udah pernah dimane aja?
