This report is a review of research submersible vehicles and other marine technologies in Siberia and the Russian Far East. It complements a 1994 WTEC report covering submersible technologies in Ukraine and European Russia. The panel found that two institutions in Vladivostok have extensive developments and experience in operating remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs). In particular, two prototype AUVs developed by the Institute for Marine Technology Problems (IMTP) are rated at 6000 meters operating depth, one of which has logged 160 working dive missions greater than 4000 meters. The WTEC panelists concluded that IMTP had more AUV operating experience than all U.S. programs combined. The panel also visited several centers of excellence in the Novosibirsk area, including the Institute of Thermodynamics and Applied Mechanics, which is world-class facility for research on aerodynamics, including eight wind tunnels achieving air speeds up to Mach 25. Other institutes the panel visited are doing research in computer software development, marine biology and bioorganic chemistry, physics, and energy research. The panel sensed a new commitment to openness about R&D work being done in the institutes it visited, and found that several institutes already have developed extensive international relationships. However, the panel also perceived that many of these institutes are in a state of crisis, with declining government funding and mixed results in efforts to spin off profit-making enterprises. Some research institutes have expired and more will cease to exist because of the lack of basic funding by the government.
