Целиком все же тут (со схемкой) :-))

US submarine comms programme passes key milestone
Tim Fish
The US Navy's (USN's) Communications at Speed and Depth (CSD) programme has passed its critical design review, Lockheed Martin announced on 12 July.
A Lockheed Martin-led industry team has been developing a real-time, two-way communications system that allows submarines to connect to the Global Information Grid (GIG) without rising to periscope depth.
"The review clears the way for the team to begin producing hardware and to deliver engineering design models in early 2011," the company said.
Partnered by Ultra Electronics Ocean Systems and ERAPSCO (a joint venture between USSI Inc and Sparton Corporation), Lockheed Martin was in January 2009 awarded a USD35.8 million contract to design and manufacture a two-way antenna buoy system. The preliminary design review was completed in October.
The team intends to deliver three variants: an Iridium Tethered Expendable Communications Buoy (TECB-I), a UHF Tethered Expendable Communications Buoy (TECB-U) and an Acoustic-to-Radio Frequency (A2RF) gateway buoy.
The TECB-I and TECB-U are launched from a submarine via a 3-inch (7.6 cm) diameter ejector tube and remain linked to the host ship by fibre-optic cable. Once on the surface, they will use Iridium or UHF satellite communications to provide real-time chat, data transfer and email capabilities.
The A2RF buoy is released from a submarine's trash disposal unit or dropped from an aerial platform, releasing an underwater array of hydrophones and projector elements to send and receive acoustic signals via the boat's sonar system. On the surface, the A2RF buoy can use military UHF line-of-sight communications for the two-way exchange of data with local units, or Iridium satellite communications to receive long-range one-way signals from a shore station or headquarters.
Meanwhile, BAE Systems is working with the US Naval Underwater Warfare Center to provide a Digital Acoustic Communications (D-ACOMMS) subsystem for use with the new AN/BQQ-10 sonar system that is being fitted in US submarines.
D-ACOMMS has been tested at ranges in the tens of miles and was demonstrated in a Los Angeles-class attack submarine as part of the Advanced Rapid Commercial-off-the-shelf Insertion (ARCI) programme. Data rates are limited but text and images can be sent using single and multiple transmissions.
Several supporting subsystems provide GIG integration into the submarine's local area network or shore-based Broadcast Control Authority systems, including a buoy interface unit, Iridium modem controller, Iridium data controller and web portal.
A number of engineering challenges must be overcome before CSD can be successfully deployed. The USN's Submarine Integration Program Office (PMW 770) told Jane's : "Deploying a relatively fragile optical fibre to the surface while the submarine continues to manoeuvre, meeting the tight volume and weight constraints for radio-frequency sections and other systems in buoys, battery technology, underwater acoustic communications integration and cryptographic integration over unconventional links are just some of the technical challenges."
PMW 770 added that two further increments for CSD include developing situational awareness capabilities and a new towed buoy system. "One increment would focus on battlespace awareness," the office said. "There are no formal requirements published as of yet, but the anticipation is that providing a capability that would give the warfighter an Automated Identification System picture, along with GPS position and possibly some type of streaming video, would be the goal.
"The other increment would focus on developing a next-generation replacement for the AN/BRR-6 towed communications buoy currently installed on SSBNs [strategic missile submarines]. The initial development effort is being pursued as a joint effort with the United Kingdom."
A request for information has been issued for the BRR-6 replacement system, which officials hope will be developed in time for installation in the USN's Ohio-class replacement SSBNs and the UK's Successor SSBNs.
