Also known as
  • M549A1 RAP

El M549A1 es un proyectil estadounidense de alto explosivo de 155 mm asistido por cohete y la version posterior, cargada con TNT, del M549 anterior cargado con Composition B. Referencias del U.S. Army lo describen como una municion de dos piezas con ojiva de acero de alta fragmentacion y motor cohete integral, construida para ampliar el alcance de obuses hasta unos 30 km y tratada posteriormente como municion heredada para ser reemplazada por el XM1113. La informacion sobre conflictos tambien situa el M549A1 RAP en uso de combate con obuses ucranianos Bohdana durante la guerra Rusia-Ucrania de 2014.

Round Architecture And Designation

La designacion A1 es importante porque las fuentes publicas la distinguen del M549 anterior por la carga explosiva y el contexto de seguridad de las cargas, no por un nuevo calibre o una nueva clase de lanzador.

CaracteristicaContexto del M549Tratamiento del M549A1
Carga explosivaLos proyectiles M549 anteriores usaban Composition B.El M549A1 usa unas 15 libras de TNT.
Motivo de clasificacion como tipoLa carga anterior estaba restringida con el uso de cargas propulsoras M203 de zona superior mas recientes.La conversion A1 fue clasificada como tipo en septiembre de 1977 para satisfacer los requisitos de seguridad de sistemas de armas de 155 mm mas recientes.
Funcion de alcanceAmbos pertenecen a la familia estadounidense de proyectiles de 155 mm asistidos por cohete.El M549A1 mantiene la funcion de alcance extendido con una ojiva de alto explosivo y un motor cohete integral.

Open munition references describe a nose-fuzed, boat-tailed steel shell with TNT or Composition B filling, while Ukrainian and defense-reporting sources document M106 projectiles being adapted to Ukrainian 2S7 Pion guns during the 2014 Russia-Ukraine War as Soviet-pattern 203 mm stocks became scarce.

Missilery describes the export-oriented projectile as a deep upgrade of the 9M55K with an inseparable HE-fragmentation head, 820 kg projectile mass, 150 kg warhead, 70 kg explosive fill, 9B708 control-system unit, and 40 to 120 km range. Rostec later listed it as Splav-produced extended-range ammunition used in Smerch launchers at SITDEF-2013.

U.S. Army ammunition records list it as an operations-and-sustainment item, Modern War Institute reporting places the M107 family in Ukraine's 155 mm ammunition mix, and U.S. emergency-sale notices document M107 deliveries to Israel during the 2023 Israel-Hamas War.

Specialist ammunition references describe a spin-stabilised, nose-fuzed projectile with an A-IX-2-filled warhead and integral rocket motor, while Ukraine explosive-ordnance identification material lists the round among munitions discovered on Ukrainian territory.
