Sinking the 15 transports.

This one for sure is tough going,is it a timed mission,
or should I ask,is your time limited to how quickly you
destroy the transports

Well I'am through this mission and the one where you need
to sink the two enemy cruisers(Admrial Hipper class)now
I'am at the one mission where you need to destroy the
six gun towers.At least now I have a cruiser so hopefully
I'll be able to get through,but so far it hasn't gone
very well.

When I went for the transports I hit them hard and fast
with both gun fire and torpedoes,I managed to arm my
destroyer with 3 barreled 12.7cm guns which did help
allot.

Did you know that for every ship type (destroyer,carrier,etc.) when you destroy 100,500,999,your rewarded cool stuff ( wave cannon is from 100 supership) double hull battleship is from 500 transports etc. I hope this is helpfull.

This is what I have so far
Rank: Admiral
Ships sunk:
PT Boat 203 Carrier 55
Transport 664 BattleCarrier 4
Destroyer 633 Submarine 117
Cruiser 478 Aircraft 571
Battleship 298 Supership 36

My Ship:
Hull: 2-Hull battleship
Defense: 56 cm plating
Speed: 50 knots
Armaments:
Tower Railgun x4
Siorc Wavegun x2
Anti air pulse x16
Anti sub missile vls x4
Aux Sytems:
Enigmatch Sturla
Electromagnetic shield B
Auto Load system B
Electronic Targeting B
Radar A
Sonar A

Im just playing now to see what beter prizes are there and as well what other tech I can find plaing the game took me awhile to get radar A....so when u see parts lying around pick them up never know what it could be. Now I just gotta find out how powerfull that wave gun is see if its powerfull than the two I got since you gotta destroy all those superships.

I just discovered how to obtain/unlock hidden weapons, hulls, equipments, etc. Once you complete 4 stages, save the game, then play the second time and try to get "S" or "A" in each mission by saving lifeboats and raising accuracy. You can aquire ultimate weapon in each mission. Those ultimate weapons are not like what you get out of the 1st round missions. Examples: D-5 (second round)-enigmatech propulsion II which speeds up your ship by 50%!, C-7 (second round)- various advanced hulls like two-hull battleship, drill battleship, xbattlecarrier which is the biggest and most powerful ship you can get, with battleship's firing power and 20 airplanes!

I read some Japanese article saying there is a super powerful wavegun which can be obtained by sinking 999 superships. Oh buoy, it takes forever to get there...

what all planes are available?

I guess I meant are all the planes the same?Are there different plane models or just one generic one?
Are there different planes for Japan, Germany, US etc.?
Do the planes evolve with tech level from like biplane -to- Wildcat -to- F-4 -to- F-14 -to- Flying Saucer?
that sort of thing.
