Russia’s New ‘AIP’ Lada-Class Submarine Has a Problem: No AIP Stealth Propulsion System So They Went Diesel Instead

Automatically curated summary from 19FortyFive.

According to analysis by 19FortyFive's Sean Spoonts, Russia’s Project 677 Lada-class submarine encountered severe design and technical failures, leading the Russian Navy to abandon its intended Air-Independent Propulsion (AIP) drive in favor of traditional diesel-electric propulsion. Intended partly for export, the submarine suffered from systemic issues, including unreliable backup generators, sonar integration problems, and hull constraints. Spoonts characterizes this project as part of a broader pattern within Russian military procurement, where complex defense systems frequently experience overpromised performance capabilities, corruption, maintenance deficits, and operational breakdowns upon deployment.
