The Forges de Tarbes is the only French industrial site still capable of producing 155 mm shell barrels. The plant has been producing about 1,500 barrels of a 155 mm caliber shell, the LU.211, which equips the dozens of Caesar guns, supplied by the France to Ukraine.

The site also plans to soon produce a more standard 155 mm, the M.107, to feed other types of guns used by Kiev because "today, we are on extraordinary needs in Ukraine"
