Transhield Cover Case Study: The MK 38 Mod 3

Case Study, Protective Covers, Transhield


The U.S. Navy’s Mk 38 Mod 3 Gun Weapon System is a stabilized self-defense weapon that dramatically improves ships’ self-defense capabilities. The system is equipped with both the 25mm M242 Bushmaster main gun and an option for a coaxially mounted 7.62mm Mk 52 Mod 0 automatic chain gun to cover all mission needs.

How we covered it 

For this cover we used our ArmorDillo® anti-corrosion fabric for heavy duty protection while at sea. The cover-fabric is waterproof, 99.9% UV ray blocking, and provides a vapor corrosion inhibitor barrier on the
equipment that protects it from corrosion up to 95%.

The cover is a 3-piece set with:

  • removable optics cover
  • removable barrel sleeve
  • removable body cover
  • easy to install and remove

MK38 MOD 3_arrowaThe removable optics cover allows the ship to keep the gun components protected while conducting surveillance in non-firing situations. The removable barrel sleeve allows for ease of maintenance on the barrel without removing the entire cover.


The Transhield ArmorDillo cover protects the Mk 38 Mod 3 Gun Weapon System from the harsh environments at sea including salt spray, dirt and grime, wind, and sun damage. The result for U.S. Navy ships has been a weapon system that’s mission ready when needed and requires less maintenance and corrosion-mitigation time.
