Integrated Communications and Advanced Networks [ICAN]

Integrated Communications and Advanced Networks (ICAN) is an acquisition strategy and systems integration process which utilizes NDI and COTS technology to integrate voice and data systems. ICAN builds upon a passive fiber optic cable plant, which has already been designed into the ship and will accommodate high volumes of information.

ICAN consolidates a number of separate, cumbersome devices and replaces them with single, multifunction, multi-purpose units. It also integrates existing analog technologies with new capabilities, resulting in valuable space and weight savings in the ship design. ICAN's four components include:

  • An integrated voice system that consolidates telephones, radios, shipboard announcing systems, sound-powered phones and intercoms
  • A machinery control system, integrating the aqueous film forming foam (AFFF) control and monitoring system, the JP-5 control and monitoring system, list control indication system and various alarm systems
  • The ship control indication system, centralizing the monitoring of ship control and navigation functions
  • The navigation critical network, which performs data distribution to users needing "time critical" navigation information.

ICAN replaces most of these existing systems' components, and replaces existing user devices and displays with new human-machine interface displays that receive and display information from the network. The end result is a ship that operates more efficiently, while requiring fewer watchstanders to monitor shipboard systems.

ICAN will be implemented on CVN 76 as a change (HMR-10) to the existing ship contract. For CVN 76, ICAN replaces the existing voice systems (Dial telephones, Intercoms, announcing systems, sound powered phones and Radio Room Interfaces), Navigation & Ship Control Systems, and Machinery Control Systems (Alarms, Vent Control Fans, JP-5 systems).

CVN 68 will receive a more limited version of ICAN during the upcoming RCOH. The extent of ICAN on CVN 68 will be to install voice, navigation distribution and possibly control and indication upgrades. CVN 68 already has a fiber optic backbone and will be receiving the Fiber Optic Cable Plant (FOCP) installation as part of the RCOH.

An acquisition strategy is being developed to backfit ICAN on the remaining carriers.

A major tenet of ICAN is the open architecture design philosophy that provides a physical infrastructure composed of signal and power transmission media, equipment racks and an uninterruptable power supply (UPS). The ICAN switching, routing, control and UPS equipment will be physically collocated in a series of centralized equipment locations known as node rooms. Our goal is to have a single, fully integrated and survivable communications core network that will accommodate growth throughout the life of the ship. Elements of system configuration and management, security and survivability are incorporated onto every layer of the architecture to ensure network integrity throughout all conditions of operation. Because ICAN is based on NDI and COTS hardware and software, user workstations can effectively and economically meet requirements for distributed multimedia communications.

While the ICAN vision is a "top down" approach, the systems engineering is being conducted from the "bottom up" to ensure the end user needs are the driving force in system design and integration. Because of the evolving nature of the technology employed by ICAN and the constraints of adding such a major change to an existing ship contract, the core engineering and the contract administration of the change are being done concurrently. The CVN 76 ICAN Execution Plan, which was made part of the CVN 76 contract with the signing of HMR-10, precludes the need for up-front specification changes and drawings. Instead, the process laid out in the Execution Plan, allows changes to the CVN 76 ship specifications and drawings to be made later via a "no cost" change process as engineering decisions are made.

To successfully accomplish the goals of ICAN, PEO Carriers and NAVSEA utilized an integrated Product and Process Development (IPPD) approach. Participants on the ICAN IPPD team included the Navy's ship design organization, the shipbuilder (Newport News Shipbuilding) and over 21 other commercial companies working together to develop and implement and execution plan to design, test, validate and integrate ICAN.

HMR-10 was signed on 16 January 1997 to implement ICAN on CVN 76. ICAN is being planned for CVN 68 as part of the upcoming RCOH.
