impact operations. For example, to conduct videoteleconferencing, an emerging important function, up to half of a ship’s other communications must be halted. Further, many units depend on the commercial Inmarsat, which is vulnerable to several classes of disruption.

Recommendation: The ASN(RDA) and NETWARCOM should immediately assign a high priority to increasing the bandwidths to every platform. Options include the following: (1) increasing the rate of GBS deployments and increasing the number of ships to which GBS is deployed; (2) investigating use of the High Frequency Automatic Link Establishment (HF ALE) to request large data transfers over the GBS satellites and for other communications coordination activities; (3) as a near-term-only capability, increasing commercial Inmarsat bandwidth to communications-disadvantaged ships to enable them to be meaningful participants in developing future network-centric operations concepts.
