M549
Sign in to saveThe M549 is a high-explosive rocket-assisted (HERA) 155 mm howitzer round developed for use by the US military in order to add additional range to standard howitzers, with a maximum range from a M198 howitzer. The projectile has two distinctive pre-assembled components—the high-explosive (HE) warhead and the rocket motor, making it a form of rocket-assisted projectile. The warhead is fabricated from high-fragmentation steel for increased effectiveness in terms of damage caused to target and contains a bulk-filled explosive (either TNT or Composition B).

==Development== The projectile was developed to provide extended range for standard and developmental howitzers. The projectile has two distinctive preassembled components—the high-explosive warhead and the rocket motor. The warhead is fabricated from high-fragmentation steel for increased effectiveness and contains a bulk-filled explosive. Currently there are two models.
