Were most of the submarines Allied or Central Powers submarines?

The Central Powers, mainly Germany pushed the U-Boat Waffe (arm of service) as the cutting edge of their naval powers, certainly not ignoring surface combatants. the Allies seemed to go more for subordinate use of the submarine, as an aid to task Forces rather than attacking them! The Royal Navy (UK) and Imperial Russian Navy pushed the idea of Fleet submarines with high surface speed, which could operate with the main battle fleet- not against it, and presumably scout about for enemy subs and underwater obstacles such as mines. The British K-boats (very accident prone) and Russian A-9 class were typical. Both were steam-electric. The a-9 could do 26 knots on the surface, operating with the task force. at siphon depth (the Russians used this term instead of snorkel)- they could charge the batteries and operate at up to 23 knots. fully submerged-mode they could only limp at 5 knots, but the tactics wee a primary force here. Fleet subs worked with the fleet- not against it. Probably the Germans fielded more U-boats than the Allies and as we have seen tactics were different. Germans favored independent raider units, Allies subordinating the subs to the surface task forces/ different tactics and arrangements. Flood l,3, 5, and 7, to come up (on an a-9 ) the code Word was (what else) ANASTASIA!- meaning in the western sense- Blow Negative! or take her up!
