Referred to as the Maritime Heritage Maritime Utility, the US Navy is currently testing 2-piece Flame Resistant garments for wear underway, in lieu of the current Coverall, which is also undergoing an FR makeover.

Testing began 14 May but the concept has been on the drawing board since last year. The Heritage variants replicate traditional sea service uniforms, with a Khaki shirt and pant for Officers and Chiefs and a Blue version for lower enlisted and noncommissioned Sailors.

Interestingly, the Blue version is similar in appearance to the old Dungarees, but one style harkens all the way back to the Dark Blue on Dark Blue of enlisted deck wear, worn up until WWII. Another option, replaces the Dark Blue shirt with a Light Blue, similar to the Chambray shirts worn until the advent of the current Navy Working Uniform.

Below, you can see all three options currently being evaluated.

Meanwhile, the Canadian Navy is considering this working uniform, displayed at the recent CANSEC by developer Logistik Unicorp. Initially it was baggier and based on a prototype ground Combat Uniform. After slimming the garment slightly, they are now working on zipper and button options.

This Canadian uniform is much closer to the Modern 2-Piece garment also being considered by the US Navy which adapts the cut of the Digital Woodland camouflage Navy Working Uniform Type III, to a similar Tan and Dark Blue color scheme of the Heritages Uniform being tested here. It also introduces FR fabrics to protect Sailors from shipboard hazards.

No matter which uniform the Navy eventually adopts, it will be Organizational Clothing, like the currently issued Coverall. Sailors will wear the Black Fleece Jacket or an upcoming FR Fleece Jacket with this uniform.
