The Navy is replacing the KG-38 used in nuclear submarines with KOV-17 circuit modules incorporated in new long-wave receivers, based on commercial VME packaging.
Both VMEbus and a BBC Micro-compatible "1MHz bus" expansion buses were provided, as was a SCSI host adapter, and an optional Ethernet interface.
Hybricon Corporation is a provider of systems packaging solutions serving the Military, Aerospace, Homeland Security, Medical and high-end Industrial markets and develops embedded computing systems and solutions for war fighter critical missions using OpenVPX, VPX, VXS, VMEbus, VME64X, CompactPCI, Rugged MicroTCA, and custom bus structures.
The OpenVPX Industry Working Group has provided new standards which will replace VME and VXS standards in future defense designs.
Carrier cards that accept PMCs are usually made in the Eurocard format, which includes single, double and triple-height VMEbus cards, CompactPCI (cPCI) cards and more recently, VPX cards.
Ultra Network Technologies products included network cards for workstations and mini-supercomputers using VMEbus connectors and fiber optic cable for the network physical connections, host network cards which resided in the network hub for Cray Supercomputers, IBM mainframes, mini-supercomputers from Convex Computer, HIPPI standard channel, and others.
