In a modern threat environment, wherein near-peer and smaller-level rivals increasingly possess precision-guided land weapons, longer-range C4ISR technology and drone weapons, increasing range is a ubiquitous emphasis across the Army and other services. Russia’s violations of the INF treaty, new S-500 air defenses, new Armata tanks and fast growing attack drone fleet - are all factors impacting Army decisions moving forward. In fact, senior Army developers specifically say that the ERCA program is, at least in part, designed to enable the Army to out-range rival Russian weapons.
The Russian military is currently producing its latest howitzer cannon, the 2S33 Msta-SM2 variant; it is a new 2A79 152mm cannon able to hit ranges greater than 40km, significantly greater than the 25km range reachable by the original Russian 2S19 Msta - which first entered service in the late 1980s, according to data from globalsecurity.org.
Last year, statements from the Ministry of Defence of the Russian Federation said that 2S19 Msta-S modernized self-propelled howitzers were fielded near Volgograd, Russia. The 2S19 Msta-S howitzers are equipped with an automated fire control system with an increased rate of fire, digital electronic charts, ballistic computers and satellite navigation systems, the report says.Therefore, doing the simple math, a 70km US Army ERCA weapon would appear to substantially outrange the 40km Msta-S modern Russian howitzer.
While senior Army weapons developers welcome the possibility of longer-range accurate artillery fire, they also recognize that its effectiveness hinges upon continued development of sensor, fire control and target technology.
“Just because I can shoot farther, that does not mean I solve the issue. I have to acquire the right target. We want to be able to hit moving targets and targets obscured by uneven terrain,” the senior Army developer said.
