Warship on the Avacha Bay could be seen quite often. The harbor of Viluchinsk, 20 km south of Petropavlovsk, is home to the Russian's largest submarine base on their eastern seaboard. It was this base that kept Petropavlovsk-Kamchatsky off limits longer than almost any other city in the former Soviet Union. The military bases are still prohibited areas in Kamchatka, not only for the foreigners, but for the locals too. There are some regulations requiring permissions for trekking from the Kamchatka KGB and military authorities. How important Kamchatka's military bases were for the Soviet Union shows the shot down of the South Korean aircraft in year 1983. 244 passengers and 25 crew members were on board. They all died. The aircraft lost its bearings and was hundreds of kilometers off the international route. After this accident GPS navigation was introduced into the civil aviation. The fishery is after the military the second biggest employer at the peninsula. The Sea of Okhotsk is said to be the richest fishery area of the world. In addition to the deep sea fishing, thousands of tons of salmon are harvested annually from Kamchatka's rivers, delivering the precious red caviar. Many big sea mammals live in the waters around peninsula. Especially common sight are schools of the killer whales. In addition to the red caviar the giant crabs are the major aspect of the Kamchatka's fish industry. The biggest species rich a diameter of 1.5 m including extremities and a weight up to 7 kg. For me tasted the crabs even more delicious than the caviar.
