The fan wiki identified the "Battlecruiser" to actually be a Kirov class heavy cruiser, after seeing reference I concur with that assessment. The Kirov class did actually possess torpedo tubes, despite the TL note, so Tanya is correctly identifying the features of the vessel where the TL incorrectly deemed it a battle cruiser (even then, a substantial proportion of battle cruisers carried torpedoes, albeit some of them submerged).
