First of all, because the navy goes to sea all the year round, the food standard is basically good, and the living conditions of submarine troops are even more difficult. They are one of the arms with the highest food standards in the whole army. After returning from combat readiness cruise at sea, soldiers often walk into the spacious and bright crew restaurant and enjoy a delicious meal.

Today's submarine soldiers' meals are already different from those of decades ago. When the submarine sails, it will still carry some fresh fruits and vegetables and a lot of canned food, and it will also bring rice noodles that it usually likes. Generally, rice noodles, vegetables and fruits are eaten first, and then canned. Of course, sometimes it's a must to mobilize the whole people to prepare dishes in jiaozi.

When all the fresh food is consumed or enters the critical period of power saving, the submarine soldiers will start to eat military cans and rations. General navy and army will design military rations in different combat environments. Navy KT-07 combination food includes compressed biscuits, beef jerky, shredded kimchi, kohlrabi, instant coffee, chocolate and chewing gum.
