New submarines platforms, in particular ocean-going submarines, potentially fitted with AIP or nuclear propulsion, have increasing requirements in terms of autonomy. With its new Black-Onyx family, Safran meets these customers' requirements by improving the autonomous navigation performance of its inertial navigation systems. Indeed, Black-Onyx family offers the highest autonomous navigation performance ever reached in the non-strategic submarines market. With Black-Onyx Dual Core family, those performances are multiplied, reaching 1Nm/120h for the most demanding applications. Finally, thanks to HRG Crystal, Black-Onyx families has the highest MTBF of the market, is maintenance-free and is a totally silent system, as discretion is key to submarine missions.
