IDENTIFICATION This document describes the functional and technical system requirements for the underwater telephone system aboard the Royal Netherlands Navy (RNLN) Air Defence & Command Frigates (ADCF). Where a conflict exists between a requirement in this specification, the content of the reference 1 to 3 and / or the General Design and Material Requirements, the requirement in this specification shall have precedence to the extent of the conflict. 2. REFERENCES [1] STANAG Minimum Standard Characteristics of Underwater Telephones for Use in Submarines, Surface Ships and Helicopters of NATO Nations. [2] STANAG 4748, Digital underwater signalling standard for network node discovery & interoperability [3] ANEP-87 Digital Underwater Signalling Standard for Network Node Discovery and Interoperability. 3. SPECIFICATION PER SUBSYSTEM 3.1 Transmitter/receiver and control unit The system shall comply with the requirements laid down in STANAG 1074 (reference 1) incl NATO standard Carrier Freq. (UWT_101) The system should comply with the requirements laid down in STANAG 4748 and ANEP 87 (reference 1 and 3) to allow the use of digital underwater communication protocols. (UWT_102) The operating / control unit shall be equipped with a graphic digital display. (UWT_103) The operating modes and parameters should be selected menu-guided by keyboard. (UWT_104) The maximum dimensions of the operating / control unit in the CiC shall be equal or less than 500 x 290 x 510 mm (width x height x depth). (UWT_105) The system shall be designed for continuous operation (in listening mode) while the ship is at sea. (UWT_106) The UWT shall be able to transmit and receive both analogue and digital underwater communication. (UWT_107) The output power of the transducer shall be adjustable at least between Pmax and (P max 25dB). (UWT_108) The system should include means for identification of friendly submarines (IFS). (UWT_109) The system shall include a headset, microphone and TTY key which can be connected on the front panel of the control unit in the CiC. (UWT_110) Commercial-in-Confidence Pagina 4/7

5 3.2 Transducers The transducer of the UWT shall suitable for installation in the position of the current UT2000 transducer in the bow mounted sonar dome of the ADCF, see figure 1. (UWT_111) The supplier shall provide the wet end cable and connectors connecting to the transducer. The cable shall have a length of at least 30 m. (UWT_112) 4. SYSTEM PERFORMANCE REQUIREMENTS 4.1 Operational modes The UWT shall have the following operational modes: Telephone (voice) mode (UWT_113) Telegraphy mode (UWT_114) Digital mode (UWT_115) Pinger mode (UWT_116) Regardless of the operating mode of the UWT the telephony mode shall be audible. (UWT_117) The system shall be able to monitor / play NATO channels in accordance with STANAG 1074 while transmitting at different frequencies. (UWT_118) The system should be suitable for use as a diver communication device. (UWT_119) 4.2 Range The transducer shall transmit omnidirectional in the horizontal plain. (UWT_120) The underwater telephone system on the ADCF shall be able to communicate with a submerged submarine in telephony and telegraphy mode at a range of at least yds in unfavourable conditions and assuming a 1 db re 1µPa bi-directional loss at the UWT carrier frequency as a result of the dampening by the sonar dome. With unfavourable conditions, conditions are meant that occur in shallow water with adverse bottom characteristics and sea state 4. Examples are the North Sea (near Devils Hole), the Skagerrak and the Baltic in the summer. (UWT_121) The underwater telephone system on the ADCF should be able to communicate with a submerged submarine in telephony and telegraphy mode at a range of at least yds under the conditions listed below assuming a 1 db re 1µPa bi-directional loss at the UWT carrier frequency as a result of the dampening by the sonar dome. The following conditions apply: shallow water with adverse bottom characteristics and a sea state of at least 3 in typical autumn conditions. Examples are the North Sea (near Devils Hole), the Skagerrak and the Baltic. (UWT_122) The supplier shall provide modelling data as well as all technical input parameters to demonstrate the performance of the underwater telephone system as part of the bid. (UWT_123) The supplier shall supply TVR and beam pattern measurement data for the first transducer. Data from previous measurements may be presented provided the supplier can demonstrate the transducers have been manufactured identically (UWT_124) 4.3 Frequency The operating frequency shall at least encompass the NATO Working Frequency (carrier frequency khz +USB modulation 300 Hz 3 khz) with both USB as LSB modulation capabilities. (UWT_126) It should be possible to communicate with units from former Warsaw Pact countries, therefore the minimum bandwidth is 8 ± 4 khz. (UWT_127) 4.4 User requirements Interface The UWT shall be able to transmit pre-recorded messages. (UWT_128) Commercial-in-Confidence Pagina 5/7

6 The system should be able to transmit messages with a time dilation. (UWT_129) The system shall have an external audio interface (0 dbm, 600 Ohm) which will be connected to the GFE ship s internal communication system. (UWT_130) The system shall allow control of the UWT through a GFE remote control HMI integrated in the combat management system. (UWT_131) It shall be possible to use the UWT for digital underwater communication by means of a GFE device connected to the UWT. (UWT_132) While using the GFE device for digital underwater communication there should be no artificial restrictions in bandwidth and source level other than restrictions against damage. (UWT_133) Speakers The UWT-installation shall provide an audio output via integrated speakers in the control unit installed in the CIC. (UWT_134) The speaker volume output shall be adjustable from 0 100% on the control unit. (UWT_135) Loggings It should be possible to log communication on an external device through an usb port on the front panel of the control unit. (UWT_136) Commercial-in-Confidence Pagina 6/7
