Russia's investment in its Northern Fleet is undiminished, says UK Royal Navy's First Sea Lord

PARIS, Feb 3 (Reuters) - Russia's investment in its Northern Fleet is undiminished, said the British Royal Navy's First Sea Lord, adding that this posed a challenge to Western powers.

"Russian investment in their Northern Fleet, and in particular, in their subsurface capabilities, is undiminished," General Gwyn Jenkins, First Sea Lord of the Royal Navy, told a naval conference in Paris.

"So despite the horrendous cost in terms of national resource and blood to Russia, of their egregious invasion of Ukraine, they have continued to pump resource into their Northern Fleet and their subsurface capabilities," he added.
