Proceedings of 14th International conference „Maritime Transport and Infrastructure - 2012”The second problem is prevention of underwater threats caused by divers’ attacks. One of themost popular solutions of this problem used by a number of World Navies is usage of underwater netscompared with floating security barriers to prevent the infiltration of intruders into the underwater partof the base. To avoid damage of warships response capabilities stationed in the Riga Naval base, it isimportant to install opening gates in the floating security system to allow warships move in and out ofthe base.For successful diver protection installation of diver detection system is necessary. Currentlythe concept of different diver protection systems available on market is more or less similar. One ofthe most popular is Underwater Surveillance and Protection System offered by Kongsberg. Thegeneral principle of the system is constant monitoring of underwater area using diver detection sonar.After the detection of potential attacker, system informs the command centre about possible attack[12]. To ensure the high level of underwater security the best solution is installing of two diverdetection units in the Naval Base in Riga. Thus, it could ensure complete sonar coverage of theunderwater area of the Base.Te third part of the naval base security system is implementing of force protection element.The solution of this problem could be divided into two parts. First part is the installation of suchequipment and weapons that can be used for destroying attacking boats, combat swimmers or detecteddiver. Force protection element must provide the possibility to affect the invader without destroying itto prevent the attack using killing power against for example wandered into fisherman.The first part of force protection element can be realized by watch personnel armament withheavy rifleman weapons to fight attacking water crafts like M2 heavy machine gun or other automaticweapons. The widely used hostile swimmer combating weapon what could be used by Latvian NavalForce Flotilla is anti diver grenades like US Navies used anti swimmer grenade.The protection of alone standing warships in unprotected harbors, ports and open sea isequally important as naval base protection. The organizing of effective defense against explosivescarrying attacking small watercraft in the open sea or standing at anchor in the port raid is possible byappliance of well organized lookout and continuous maintenance of response readiness by all kinds ofweapons. The organization of armed night watch on the ships exterior decks in the hostile waters andports is necessary. View of the fact that being out of the well secured naval base warship is not able touse base stationary diver detection system any warship must have capability of organizing diverdetection wherever located by other methods. The one of the solutions is use of the DSITTechnologies Point Shield Portable Diver Detection Sonar. Despite the small size this is full-fledgeddiver detection sonar which bigger version of DSIT Technologies Aqua Shield Diver Detection Sonarwhich is used for port and harbor protection from underwater attack threats [13].ConclusionsThe Republic of Latvia as the member state of NATO and the participant of internationalmilitary operations must be defined as potential terrorist attack target. The up growing terrorism levelin the Europe and Baltic countries increases terrorist attack possibility in Latvia. Latvian Naval ForceFlotilla must follow technological progress and apply new inventions to solve security problems.Liepāja Naval Base is not recognised as a secure base for warships trimming, but it should bereconstructed and secured in accordance with the NATO standards. The security system of the waterbasin of Latvian Naval bases must be composed of three security elements – surface security element,underwater security element and force protection element. The protection of alone standing warshipsin unprotected harbors, ports and open sea is equally important as naval base protectionReferences1.
