ADDENDUM 



1) Figure 2.1 is incorrect in the following areas: 



a) Only two (not six) RCV-150 vehicles have been constructed 



b) Two RECON Ill's have been constructed in 1979 and two more are scheduled 

 for construction in 1980. 



c) The U.S. Naval Undersea Warfare Engineering Station, Keyport, Washington 

 is scheduled to take delivery of the TROV 10 vehicle in November 1979, 

 the vehicle will be redesignated URS-1 (Undersea Recovery System) . 



2) Technomare is in the process of finalizing TM 402, a bottom crawling vehicle 

 designed specifically for trenching cable and small diameter pipe. It is capable 

 of digging trenches up to 0.4m (1.3 ft) wide and 1.5m (4.9 ft) deep and buries 

 pipe up to 0.3m (1 ft) diameter. The machine weighs 22 metric tons in air and 



is 11m (36 ft) long and 5.6m (18.4 ft) wide. It is propelled by caterpillar-like 

 tracks and is powered and controlled from the surface. Development of this 

 vehicle and its predecessor, TM 102, was provided by a grant from the European 

 Economic Council. 



3) The capabilities listed under Vickers Oceanics Ltd. (SEA CAT) , now operate 

 under the title of British Underwater Engineering. 



4) Solus Ocean Systems has adopted and modified a color TV for application 

 from its TREC vehicle. The device has been used for inspection of an oil 

 platform in the Gulf of Mexico. Tapes from this system have been reviewed 



by Busby Associates and show good color rendition at ranges up to approximately 

 Im (3.2 ft) (under 400 watt quartz iodide lighting). Selected specifications 

 of the color TV camera are: 



Color System: NTSC-type output, phase and frequency separation system. 



Vidicon Tubes: Single tube system, 25mm (1 in.) VIDICON with specially 

 designed Striped filter. 



Scanning System: 525 lines, 60Hz, 2:1 interlaced. 



Video Output: IV p-p, 75 ohms through 12-pin camera cable connector. 



Resolution: More than 230 lines (horizontal) , more than 300 lines (vertical) . 



S/N Ratio: More than 40 dB (Y channel) , 30 dB (chroma channel) . 



Audio Output: -20 dB/low impedance (through 12-pin camera cable connector). 



Lens: Normal fixed lens 25mm, f 1.8 variable focus. 



5) Additional details of the RCA color TV system discussed under Section 6.1.2 

 have been published in the July 1979 Institute of Electrical and Electronic 

 Engineers publication Spectrum . The following is taken from that periodical: 



"A solid state camera with three charge-coupled devices (CCDs) as image 

 sensors for each of the primary colors of television — red, blue, and green — 

 has transmitted detailed color TV pictures from a submarine engaged in 

 oceanographic exploration at 9000-ft depths. The prototype camera, 

 specially configured by RCA's Electro Optics and Devices Div. for a National 

 Geographic expedition, was mounted outside the submarine on a mechanical 

 arm. Among the filmed marine life were pictures of giant eight-foot long 

 tube worms that scientists say represent a basic division of the animal 

 kingdom because of the novel anatomy. Each image sensor of the tubeless 

 camera comprises a matrix of 512 x 320 elements for a total of 163,840
