Shipyards in Saint Petersburg are back at it. Admiralty Shipyards just laid the keel for yet another Project 677 Lada class submarine, named the Maloyaroslavets.
If you follow military shipbuilding, you know the Lada project hasn't been a smooth ride. It has faced decades of delays, redesigns, and conflicting statements from corporate leadership. United Shipbuilding Corporation held a keel-laying ceremony that sparked immediate confusion. Their own press materials called the Maloyaroslavets the sixth ship in the series, while CEO Andrey Puchkov publicly referred to it as the fifth. Nobody bothered to clear up the discrepancy. That kind of messy messaging tells you a lot about how Russian defense procurement actually functions behind closed doors.
Let's look past the corporate confusion and examine what this vessel actually means for the Russian Navy.
The Long and Troubled Road of Project 677
The story of the Lada class starts way back with the lead boat, the Sankt-Peterburg. That submarine entered extended trial service way back in 2010. It was a disaster of a development process. Engineers realized the initial design had massive shortcomings in propulsion and sonar capabilities.
Instead of mass-producing a flawed hull, Moscow hit pause. The Rubin Design Bureau went back to the drawing board. They overhauled the design completely, tweaking everything from acoustic signatures to internal combat systems.
It took years. But that painful trial-and-error phase gave birth to the modernized variants we see today. The Kronshtadt joined the fleet in 2024, followed by the Velikiye Luki in 2025. Now comes the Maloyaroslavets.
What Makes the Lada Class Different
You might wonder why Moscow cares about conventional diesel-electric submarines when they have nuclear giants roaming the oceans. Quietness is the answer.
Nuclear submarines run hot. Their coolant pumps create a distinct acoustic hum that modern passive sonar can pick up from miles away. Diesel-electric boats running on battery power during slow patrols are virtually silent ghosts.
United Shipbuilding claims the Lada class features an exceptionally low acoustic signature, advanced sound-dampening coatings, and a powerful sonar suite. They boast that it outperforms foreign competitors of a similar size. Of course, they haven't shared hard metrics or independent sensor data to back that up. You have to take corporate defense claims with a heavy grain of salt.
Even so, naval analysts generally agree that modern AIP (Air-Independent Propulsion) or advanced battery-electric boats pose a serious headache in shallow coastal waters and choke points like the Baltic or Black Seas. They don't need to cross oceans. They just need to wait quietly in ambush.
The Production Reality Check
Laying a keel is easy. Finishing the submarine is where things get complicated.
Russian shipyards are currently stretched thin. Defense spending is heavily skewed toward immediate frontline needs in the ongoing war in Ukraine. Surface combatants, artillery, and drones consume massive manufacturing capacity.
Can Admiralty Shipyards maintain a steady cadence for these conventional submarines? History suggests delays are practically guaranteed. Component shortages, electronic supply chain bottlenecks, and industrial sanctions loom large over every Russian defense sector project.
When you look at the big picture, the Maloyaroslavets represents an ambitious effort to modernize Russia's underwater fleet despite immense systemic friction. Whether it enters service on time—or slips by years like its predecessors—will tell us a lot about the true endurance of Russia's defense-industrial base.
Keep an eye on shipyard updates over the next two years. If hull modules start appearing ahead of schedule, Moscow's production lines are adapting. If things go silent, you'll know the old bottlenecks are back.
