Technical Notes on the Near Surface Experiments of Submerged Submarine

In this study, the experimental analysis on the bare hull resistance coefficient of submarine at snorkel depth is represented. The experiments are conducted in marine laboratory of Admiral Makarov University. The results are presented for surface condition and snorkel condition. Snorkel depth is regarded equal to one diameter of submarine hull beneath the water surface as usual in submarines. P...

Exploratory in nature, this study was designed to identify some of the personality trait configurations and attitude change patterns related to individual differences in cold coping capacity (CCC). Three enlisted marines participated in a week-long cold weather North Atlantic Treaty Organization (NATO) combat exercise in upper Norway. The Minnesota Multiphasic Personality Inventory (MMPI) was a...

Plasma vitamin C levels were determined for 28 submariners prior to, during, and after a 68-day patrol. A significant reduction occurred in plasma vitamin C levels during the patrol compared to levels obtained before and after the patrol. These reductions were unrelated to health and performance effects as determined by total dispensary visits, frequency of upper respiratory infections, and tra...

Submarine Capability Optimisation

Procurement of high value defence assets, such as ships, submarines and aircraft requires rigorous analysis to ensure the system procured will perform as required in the operation. To achieve this, system and subsystem modelling can be conducted to determine how the subsystem choices affect the whole system performance. This should be linked to a capability analysis to relate the subsystem perf...
