The K-83 Danilov is a Soviet-built submarine.
History[]
Interceptor[]
At an unknown time, the K-83 Danilov came to be Captained by an unnamed Russian Navy operative.
Later, the Captain of the Danilov was contacted by the leader of a terrorist group, who bribed him into agreeing to use the Danilov to extract a group of mercenaries who were aiding them in bringing down the SBX-1 nuclear missile interceptor platform, as part of their long-term plan to launch a nuclear missile attack on the United States.
For months before the operation was to take place, the Danilov lurked in the waters of the Pacific Ocean near SBX-1 (presumably to scope out the area in advance), and the Captain had his crew continue to return to the area whenever U.S. naval vessels drove them away. The submarine's actions confused the commanding officer of SBX-1, Lieutenant Colonel Clark Marshall.

When Captain JJ Collins arrived at SBX-1, Marshall inquired Captain Lou Welsh to get him an update on the Danilov. Soon after, when an incident occurred at Fort Greely, Marshall asked Corporal Beaver Baker about the Russian submarine, with Baker replying it was still circling them before Marshall explained the Danilov's curious activity the past several months.
After Alexander Kessel made it inside the command center of SBX-1, he had the terrorist leader contact the Danilov's Captain to tell him to have "Danny" move in for his team's extraction. While it was moving in, however, Kessel was forced out of SBX-1's command center, and soon Kessel was forced to resort to his backup plan of sinking SBX-1 altogether. Once the process had begun, he called the terrorist leader to inform him that it would take 12 minutes before he would be clear to launch the remaining nukes. The terrorist leader then apparently informed Kessel that the Danilov was not yet near SBX-1 for their extraction.
The approach of the K-83 Danilov soon set off a proximity sensor in SBX-1's command center. Seeing this and recalling Kessel's earlier phone call regarding "Danny", Collins figured out the mercenary's intent to use the Danilov to escape the interceptor platform.

When Kessel's failure resulting in all of the terrorist missiles being destroyed mid-flight, the terrorist leader contacted the Danilov's Captain to order him to eliminate Kessel instead of extracting him. The Danilov surfaced next to the nearly sunken interceptor base, the sight of it bringing relief to Kessel since he believed its arrival meant he would escape. But after the Captain emerged onto the Danilov's open deck, a sniper he had brought with him took aim at and shot the mercenary. After the Captain give the surprised Collins a slight-tip of his hat, he re-entered the Danilov and had it depart the area. Choppers carrying SEAL reinforcements noted its departure as they made their final approach to SBX-1.
