In this study, the effect of stationary fin and buoyancy devices on dynamic pithing of the tracked vehicle was investigated. For this work, the stationary fin and buoyancy devices were installed in front of body and then pitching variation was measured when rapidly reducing the vehicle speed in water operation. According to the results of measuring the freeboard at each case, when only fin was installed, the effect on freeboard of tracked vehicle in water was negligible. However, when buoyancy devices were installed, front freeboard was approximately increased by about 20~25 mm and rear freeboard was decreased by about 10~15 mm per each addition of 100 kg buoyancy device. Based on the calculation result of pitching decrease rates, it was found that the pitching variation was decreased approximately 12.3 % by fin installation and approximately 2 % by installation of each 100 kg of buoyancy device. The case in which only fin installation was made showed the best efficiency in decreasing pitching variation of the tracked vehicle in water compared to the other cases.
