DSCS SHF continues to provide the Navy with the required global connectivity among fleet units, joint forces, allied and NATO forces, and Naval C4I commands. Currently, SHF capability is deployed on Numbered Fleet Commander flagships, CVNs, flag-capable amphibious ships, and SURTASS platforms via the AN/ WSC-6( V) 1 through AN/ WSC-6( V) 4 SHF SATCOM terminals. The DSCS SHF requirement will be expanded to all LCCs, AGFs, SURTASS, CVs/ CVNs, LHAs/ LHDs, flag-configured and new construction LPDs, TOMAHAWK or AEGIS-capable CGs/ DDGs/ DDs, CLF ships, and Mine Countermeasures Support (MCS) ships. SSNs also require a wideband capability provided in conjunction with the modified high data rate (SUB HDR) program.

The AN/ WSC-6( V) shipboard terminal is designed for use on surface ships to satisfy the Navy SHF ship-to-shore communications requirements while remaining within the cost, weight, and size constraints of the shipboard environment. The AN/ WSC-6( V) consists of the radio group and the antenna group. The antenna group is configured in a single or dual configuration to give 360 degrees of antenna coverage.

AN/ WSC-6( V) Technical Characteristics

Among the menu of services via DSCS SHF are the DISN, GCCS, JMCIS, Contingency Tactical Air Control System (TACS) Automated Planning System (CTAPS), Advanced Narrowband Digital Voice Terminal (ANDVT), STU-III, PC-to-PC transfer via STU-III, TADIXS, broadcast record message traffic, Manual Relay Center Modernization Program (MARCEMP), TOMAHAWK Mission Planning packages and updates, imagery support, Defense Switched Network (DSN) telephone/ Integrated Services Digital Network (ISDN) access, JDISS, JWICS, Unclassified But Sensitive and Secret Internet Protocol Router Network (NIPRNET and SIPRNET), VIXS/ VTC, SALTS, and TESS/ Navy Integrated Tactical Environmental Subsystem (NITES).

The AN/ WSC-6 terminal variant supports a non-AJ data rate of 64 kbps (threshold) to 1.024 Mbps (objective) for nonflag-capable ships, and a combined non-AJ data rate of 768 kbps (threshold) to 2.048 Mbps (objective) for flag-capable ships. SURTASS terminals support data transmission at 9.6 kbps for shore-to-ship circuits and 144 kbps for ship-to-shore transmission. Terminal variants installed on flagships and flag-capable ships will be capable of supporting jam-resistant communications with the addition of an AJ modem, such as the UMS.

The estimated numbers of SHF terminals to be deployed and to be used for training/ testing are as follows:

Fleet Commander flagships 4
SURTASS platforms 10
Aircraft carriers (CVs/ CVNs) 12
Amphibious force flagships (LHAs/ LHDs) 11
Flag-configured LPDs 2
New construction LPDs 2
TOMAHAWK or AEGIS-capable CGs, DDGs, and DDs 108
Combat logistic force ships (CLF) 13
Mine countermeasure support ships (MCS) 1
SSNs 55
Shore trainers 2 per variant
Testbed terminals 1 per variant
SURTASS trainer 1

AN/ WSC-6 Installation Steps. The AN/ WSC-6 terminal installation will be provided in three evolutionary steps.

Initial operational capability (IOC) for Step 1 was achieved in FY 1997, IOC for Step 2 is scheduled for FY 1998, and full operational capability (FOC) is expected in FY 2006.

FY96 funds procured mod kits and miscellaneous equipment to modify four AN/WSC-6(V)4 terminals to allow dual channel capability. Existing Navy and Army contracts were used. A new production contract will be awarded in FY97 for SHF AN/WSC-6(V)X terminals including non-recurring costs, first article testing and delivery of three units. FY97 funds also procure four seven foot antennas to replace existing four foot antennas and will procure mod kits for installation on 9 AN/WSC-6(V)2 and AN/WSC-6(V)4 terminals. The seven foot antenna procurement is a separate contract; the mod kits are bought on the antenna contract and two existing Army and NRAD contracts. FY98 and FY99 funds procure additional AN/WSC-6(V)X terminals, AN/WSC-6(V)2 and AN/WSC-6(V)4 mod kits, additional seven foot antennas and production support.
