| Summary: | Approved for public release, distribution unlimited === The U.S. Navy has recently embarked on a program called Next Generation Computer Resources (NGCR) whose aim is a cooperative effort between Navy and industry to field a set of state of the art computers for shipboard use in the late 1990's. One of the important features of NGCR is the use of commercial hardware developed to standardized protocol and ruggedized for military applications. This protocol provides for compatibility between machines. The machines themselves may be of any architecture so long as they can meet the protocol requirement as specified by NGCR protocol, while not fully defined, implies the use of microprocessor based workstations. The Naval Sea Systems Command in an effort to keep pace with combat system software, desires experience in developing software targeted for commercially available NGCR machines (workstations). This study provides a detailed set of initial requirements for such a system. The approach is to implement the basic features of a Combat Direction System (CDS) on a microprocessor based workstation. This low cost CDS (LCCDS) will initially be installed on non-combatant vessels which currently have no computer processing capability at all. Eventually the LCCDS may be used to augment current processing capability of CDS equipped combatants followed by future systems designed around high speed (SAFENET) networks of tactical workstations.
