FX is staying the course with The Americans.

The low-rated but critically acclaimed 1980s Russian spy drama has been renewed for a fourth season, the cable network announced Tuesday.

Starring Keri Russell, Matthew Rhys and Noah Emmerich, the fourth season will return in 2016 with another round of 13 hourlong episodes.

"Remarkably, this season of The Americans has achieved even greater acclaim than that of its first two seasons," FX original programming president Nick Grad said. "The series has cemented it status with critics as television’s best current drama and arguably the best show on TV, and we couldn’t agree more."

Season three of the series, produced by Fox 21 Television Studios, FX Productions and showrunners Joe Weisberg and Joel Fields, has been on par year-over-year, drawing 4.2 million total viewers (down 4 percent) and 1.8 million among adults 18-49 (off 6 percent) when factoring in seven days of DVR viewing, VOD and streaming. Season three has seen the series grow 147 percent from its overnight performance when adding seven days of viewing (up from 124 percent in season two and 93 percent in its freshman run).

The Americans joins a drama roster at FX that also includes Tyrant, The Strain, Taboo and the farewell season of Justified as well as anthologies American Horror Story, American Crime Story and Fargo.
