In 2005, the Mk 6 began to be replaced by an evolution of the original design, the Mk 6A helmet. NP Aerospace also manufactures the Mk 6A Although it looks very similar to the Mk 6, the Mk 6A has enhanced ballistic protection and is marginally heavier than the earlier model.[v
My helmet is made in 2007.
