"This year there has been less intensity of Russian activity as compared to BALTOPS 2015, nothing like the close flyby of the [destroyer] Donald Cook in April," Foggo said in a Wednesday interview with reporters.
The exercise features U.S. warships, including dock landing ship Carter Hall, and Marines with 3rd Battalion, 8th Marines who landed their amphibious assault vehicles on a beach at Uto, Sweden.
"We characterized that as unsafe and unprofessional, and I don't think they want to be seen that way," Foggo said.
The interactions between Russian and NATO forces during BALTOPS have been professional, Foggo said.
BALTOPS is a two-week annual exercise where NATO practices all the major warfare areas. This year the group is focusing on heavily on amphibious operations and anti-submarine warfare, Foggo said.
The Russian military is planning to do a fast-reaction exercise called a SNAPEX but there are no details on the maneuver just yet, he said.
Notably absent from the exercise thus far are Russian submarines. Foggo said the Russians have not been observed or detected during the exercise.

Foggo, who is a career submariner, has sounded the alarm on Russian undersea activity, telling Navy Times in October that Russia's capabilities were growing.
"The Russians have always fully funded their submarine capabilities and as they've evolved, they've become better," he said. "They've become quieter and more capable adversaries. So we need to watch that more carefully and we need to watch our presence in the undersea domain."
