Infodefensa specifies that this shipment represents “an important qualitative leap in terms of capabilities.” this artillery allows you to attack from a long distance, both to enemy forces located in the vanguard and those located in the rear.

History of the M109

The M109 is an American-made howitzer and came into use in the 1960sbeing used since then in conflicts such as the Vietnam War, the Yom Kippur War, the Iran-Iraq War and the Gulf War.

To Spain these howitzers arrived in 1978 and, after numerous updates, the Spanish Army still has 90 M109 A5 units. The Marine Corps, meanwhile, has six units on loan. There are no plans to replace the M109 A5 at the moment, but an update is underway it would imply the substitution of the tubes by other second-hand American ones with the chrome bore.

The M284 tube, currently in service, is being replaced by the M284 A2 tube which, apart from having the bore chromed, has implemented a solution that prevents the erosion of the bushing evacuator holes.

The Army would be considering replacing the M109 fleet, but it would not be a priority. The United States Army has an even more modern version, the M109 A7 Paladin, although at the moment it seems that other solutions would be chosen, such as the digitization of the equipment of the M109 A5 howitzer or the possible use of ammunition Excalibur. This type of ammunition has a range of between 40 and 55 kilometers, but would be used by the 155/52 SIAC howitzer.
