you can destroy almost the entire UK fleet in Scapa Flo with CAS and TAC sustained attacks. Keep the carriers just outside the port, and don't use them in the attack!
Agree! I believe that the TAC are way too destructive against ports (and even open sea provinces). The sea provinces should be the domain of the carriers and NAV bombers, not TAC. As for the CAS, well that I would leave as is since they are a very destructive force. How often do CAS get the ability to attack ships? You don't see the UK porting ships in its southern ports when France falls because they are within range of CAS in France.
Here's the navalattack parameter breakdown between Naval Bombers, Tactical Bombers, and CAS:
Bomber | navalattack | navalattack | Bomber | navalattack | Bomber |
| | 0.5 | Great War Bomber (1918) | | |
| | 1 | Interwar Bomber (1928) | | |
| | 2 | Early Bomber (1934) | | |
Basic Naval Bomber (1938) | 4 | 3 | Basic Tactical Bomber (1937) | 4 | Basic CAS (1937) |
Improved Naval Bomber (1941) | 6 | 4 | Improved Tactical Bomber (1940) | 6 | Improved CAS (1940) |
Advanced Naval Bomber (1943) | 8 | 5 | Advanced Tactical Bomber (1943) | 8 | Advanced CAS (1943) |
Turbojet Naval Bomber (1945) | 10 | 6 | Turbojet Tactical Bomber (1945) | 10 | Turbojet CAS (1945) |
Improved Turbojet Naval Bomber (1949) | 12 | 7 | Improved Turbojet Tactical Bomber (1948) | 12 | Improved Turbojet CAS (1947) |
| | | | 14 | Modern Jet CAS (1955) |
As we can see, the navalattack parameter is simply done. The CAS and Naval Bombers have the same navalattack for comparable (or close to) years and increments by two for each new bomber level. Whereas, the Tactical Bomber increments by one for each level (except 1918 to 1928 by only 0.5). If we look at the beginning of the Battle of Britain (1940), there is only a difference of two between Tactical and Naval/CAS. However, how many nations have 1940 level Tactical and CAS in 1940, let alone 1941 Naval? So I think we should not tweak any Tactical, CAS, or Naval bombers but look elsewhere for tweaks.
It's just amazing to me how ineffective Pearl Harbor-type CV attacks are, vs how devastating land-based bomber attacks are.
MJF has hit the issue on the head. The carriers, actually the CAGs, should be the destructive power of the navy. Before going further, we need to know how divisions, brigades/attachments, and the different unit types coexist (I know that this is basic knowledge for most but for it's for those that don't know it):
- Divisions - The term is not actually army divisions but units that are not brigades. They are independent units that can be place into the game(e.g. ships, plane, etc.).
- Brigades - These are dependent units that require a division before they can be placed into the game. They are the attachments (MPs, Engineers, Artillery, Fire Control, etc.)
- Currently, there are 3 unit types in the game For a brigade/attachment to be attached to a division, they must be the same unit type and the division allowed to use that brigade/attachment:
- air_unit_type
- land_unit_type
- naval_unit_type
Why the history lesson? Because there are difference parameter/statistics between the three. Getting back on track with the carrier/CAG issue, air units use a different parameter for bombing naval targets, navalattack for air units and seaattack for naval units. Although we think of the CAGs as air units, they are not. They are naval units and use the seaatack parameter. Carrier bombing utilizes two parameters types to determine damage, seaattack against ships (except subs which they have subattack) and shorebombardment (yes CAGs bombs shores) against air bases. Since the issue we're talking about is a Pearl Harbor type event (bombing ships), we're going to focus on the seaattack parameter.
When a port strike mission occurs, it uses the CAG's seaatack parameter against the ships in port. The 1941 CAG, currently researched through the Advanced Air Carrier (1941), has a seaattack of 8. These numbers assume that the attacking nation has 1941 CAGs in 1941. The carrier has a build time of 180 days (6 months), so it's highly unlikable that any nation would have this except for Japan and they might have one due to the time to research the carrier technology and the time to upgrade the CAGs. We'll use an Improved Air Carrier (1938) carrier. The Improved CAG (1938) has a seaatack of 6. Now let's compare a 1938 CAG against a Great War Battleship (1918), Great War Battlecruiser (1918), and a Great War Heavy Cruiser (1981). A 1918 Battleship has a seaattack of 11, a 1918 Battlecruiser has a 9, 1918 Heavy Cruiser has a 6, and the 1938 CAG has an 6. Yes, looking at this one thinks that a 1918 Battleship and 1918 Battlecruiser are more powerful than the aircraft carrier CAG and the 1918 Heavy Cruiser has the same, all are true. But we must factor in the 1938 CAG's surfacedetectioncapability (ability to target enemy ships) and distance parameters. The surfacedetectioncapability is a huge advantage for the CAG but it's the distance (not to be confused with a naval unit's range...distance they can travel before refueling/resupplying) that makes the CAGs so lethal against ships, at sea. If we were to make the CAG's surfacedetectioncapability, distance, or seaattack higher values, many more ships would be at the bottom of the sea whether the enemy ships are in port or not. It's the task_efficiency for port_strike that matters.
Task efficiency for port strikes and air bases can currently be increased through the Naval Doctrines. The game has a task efficiency, for any task types, 0 through 1.0. Currently, the highest levels you can obtain for port strike and air base strike is 0.5. The game has three separate naval doctrines one can research. I'll call them UK (the left side of the Naval Doctrines screen), USA (the middle of the screen), and German (the left of the screen) for ease. The ability to conduct port and air base strikes is in the Fleet Auxiliary Carrier Doctrine which is required for any of the three doctrines. The worst doctrine to follow for air base and port strike operations is German. As one researches through this doctrine, they will accumulate only 0.1 in task efficiency in port and air base strikes with the Subsidiary Carrier Role Doctrine (1939). The UK path will accumulate 0.3 task efficiency in port and air base strikes with 3 doctrines. The USA path will accumulate 0.5 task efficiency in port and air base strikes with 6 doctrines. We could create a new technology tree to increase the task efficiency for both strike types but we could only increase it by a total of 0.5 since we have to consider all three doctrine types to stay within the 0 to 1.0 allowable range. If we did it this way, the UK path could increase to 0.8, the German path to 0.6 and the USA path to 1.0. Is this fair? Does it simulate real life?
No it doesn't. So the best way is to separate the port and air base strike efficiencies from their currently located doctrines into a separate technology tree or a separate CAG technology tree that any nation can research to any level they want up to 1.0. I think the best way to do this is a new CAG technology tree that increases the task efficiencies. What are your thoughts?
