Always reliable, always evolving

Originally developed as the T63 to meet a US Army requirement for a 250 shp turboshaft, the Series I M250 has spawned an entire family of small turbine engines.

The recently introduced Value Improvement Package (VIP) kit gives Series IV operators a post-production option to improve performance by five percent. A FADEC upgrade program will also deliver improved capability and reliability.
