The Neustrashimy-class frigates were designed as Soviet anti-submarine hunters that survived the Cold War

In short: Originally planned as a seven-ship fleet of advanced anti-submarine warfare frigates, the Neustrashimy class faced a turbulent transition after the Soviet Union collapsed. Today, these vessels remain active in the Russian Baltic Fleet, having evolved from Cold War hunters into modern platforms for international patrols and complex maritime exercises.

The Neustrashimy class, designated Project 11540 Yastreb or hawk, was conceived in 1986 to serve as a general-purpose anti-submarine warfare frigate, succeeding the Krivak-class vessels. The ships were equipped with the Zvezda-1 integrated sonar system, known by NATO as Ox Tail, to detect underwater threats. Construction took place at the Yantar Yard in Kaliningrad, but the dissolution of the Soviet Union severely disrupted the program. While seven ships were initially planned, only the lead ship, Neustrashimy, was completed by the time the Soviet Union fell.

The fate of the remaining hulls varied significantly. The second ship, Yaroslav Mudry, was eventually completed and began sea trials in 2009. A third vessel, Tuman, faced a different path; work was suspended in 1993 when it was roughly 47% complete due to funding shortages. After being launched in 1996 and laid up in 1998, the shipyard director announced in 2016 that the incomplete hulk would be scrapped, as finishing an outdated design was deemed inefficient compared to modern alternatives. The Neustrashimy itself underwent a lengthy refit starting in 2014, complicated by the need to source parts for its Ukrainian-made engines, before returning to service.

In operation, these frigates have been deployed far from their Baltic home. In 2008, the Neustrashimy was sent to the Gulf of Aden to combat piracy, where it cooperated with international forces, including the Royal Navy, to protect merchant vessels like the MV Powerful and MV Rabih. Yaroslav Mudry has also maintained a high operational tempo, participating in the INDRA-2019 exercise, visiting ports in Cyprus, India, Oman, and Sri Lanka, and conducting maritime patrols. The legacy of the class continues through the United Shipbuilding Corporation's Project 11541 Korsar, an escort ship design derived from the Neustrashimy architecture that offers modular armament options, including Kalibr or Oniks missile systems.
