All database editing was done with DWEdit by Ludger, without whom this mod would not have been created.
The purpose of this mod is, straightforwardly, to address the aspects of DW game-play that most bother its authors, while improving the simulation experience and fixing bugs, without introducing any new ones. Thank you in advance for downloading this mod. Please send as much feedback as you can via the dedicated thread on the
www.subsim.com mod forum,

TO INSTALL: Run the self-extracting .exe installer and follow the on-screen installer prompts. After installation, enable LWAMI using the JSGModEnabler.
NOTE: Saved games created with one Database and Doctrine set are not compatible with any other versions of the database, however, you can restore a previous version of the Database and Doctrine folders at any time to load saved games associated with that database. Saved campaigns are associated with your player profile and are not affected by game or database version. Please note, the charts and graphs previously included with this mod are now out of date, and will be updated in a separate release.
XX-Changes for LWAMI 3.09-XX
BUG FIXES
The sub-launched ASCM/CIWS bug has been corrected by sacrificing TIW alerts for sub-launched antiship missiles. Strike missiles, SUBROCs and the SS-N-22 retain the TIW alert (and the CIWS bug). The SS-N-27 ASM retains the TIW also, as only the 1st stage of the weapon suffers from the CIWS bug; the terminal stage is engaged normally. The weapons chosen to retain the TIW alert are those which are unlikely to be successfully engaged by the CIWS, and thus having the TIW alert is more important for the FFG driver.
A new helo dipping doctrine is used to reduce the frequency of helicopters pinging during takeoff/landing.
NEW OBJECTS
LWAMI welcomes the following navies (in part) to the world of DW: Canada, Chile, Italy, The Netherlands, Norway, Singapore, South Africa, and Sweden!
Subs: Alfa, Valiant, Oyahsio, Scorpene, Challenger (Sjoormen), Yushio, Oberon,
Sauro, Charlie I and II, Delta III, Gotland, Hotel, Le Triomphant, Mike, November,
Romeo, Swiftsure, Ula, Vastergotland, Virginia, NR-1, Ben Franklin, Skipjack,
Sturgeon, Permit (Thresher)
Ships: Whidbey Island, Hauk, Skjold, Stalwart, Kidd, Udaloy II
Installations: SA-2 Site, Spoon Rest Radar, SCUD Launcher (full and empty; NOT
functional at this time), sub drydock (empty and full), SSM Batteries (Brahmos,
Moskit, C802, and Exocet)
Torpedoes:
DM2A3 (35kts/20km), Black Shark (50kts/40km),FFV Types 613 (ASUW, passive, 45kt/15km) and 431 (ASW, A/P, 30kts/20km), Mk 48 (early) (55kt/38km), A-184 (36kt/12km)
Missiles:
SS-N-7, SS-N-9 (sub launched), SS-N-21, SA-N-3, SA-2, NSM, BrahMos, Gabriel
Aircraft:
COMSAT (The COMSAT is meant to be an omnipresent ESM source. To use, position the COMSAT about 200nm from the action at an altituve of 99,000ft; assign it an adequate speed and put it on a barrier or perimeter box tactic such that its bearing will not change relative to platforms in the mission area. Mission designers may use this object to allow playable units (not using autocrew) to trigger scripts, among other uses.)
Other:
DownedPilotBeacon: This object supplements the regular Downed Pilot; it does not replace it. DPB contains a "distress beacon" sensor that will appear on ESM. Mission designers now have the option to use either object (or better yet, can use both to simulate the beacon being activated at a time of the designer's chosing).
OBJECT EDITS
Sakura-mod fixes have been implemented to the Oil Rig. The Oil Rig is now treated as a civilian vessel in the mission editor (and will appear as a ship rather than a land-based entity on NAV). Any use of the Oil Rig should be in a 0-current, 0-wind zone to prevent the rig from drifting. These edits allow the oil rig to be targetable by SSMs.
Active Sonar SLs have been rescaled based on the mass of the sub and the presence of anechoic tiles. The primary impact of this change will be on very small SSKs (<2000tons), which will be harder to detect with active sonar and more difficult for torpeodes to acquire. Values for medium sized subs are about the same, and higher for larger subs.
Active Sonar SLs for mines and torpedoes have been sharply reduced. MF Active sonar is no longer effective for minehunting; HF active sonar must be used.
Active sonar sensitivity for the Seawolf and 688I have been reduced slightly to make performance more comparable to that of surface ships and to make standoff Kilo hunting somewhat less practical.
SLMM and Mobile mine PSL reduced to be comparable to D-E subs.
DM2A4 Torpedo has had its stats adjusted (de-nerfed from DM2A3 values); 50kts/45kyd
USET-95 torpedo speed and range adjusted to 30kts/14kyd.
SUT torpedo edits: 35kts/13.4km
ASROC range extended from 5 to 15nm
Land Based objects given IR SLs.
Bear's tailgun now faces aft instead of forward.
Pillboxes now have an SA-14 launcher. Beware.
Spruance DD ESSM launcher position adjusted so that the missiles are no longer launched from underwater.
Russian SAM effectiveness ratings have been adjusted:
SA-N-1: 30
SA-2: 40 (not anti-missile capable)
SA-N-4: 30
SA-N-6: 60
SA-N-7: 40
SA-N-9: 75
SA-N-11: 65
These values (except for the SA-2) are meant to represent anti-missile percentages, rather than anti-aircraft, because their usual use in DW is anti-missile. Note that the previous value for the SA-N-9 was 100, so some ships once thought to be invulnerable to missile attack are now just very hardened.
Noteworthy Loadout changes:
Type 206: DM2A3 has replaced DM2A4
Grisha: USET-80 has replaced UGST
Neustrashimyy and Kirov now fire SS-N-15s from their torpedo tubes
Yugo SSM: SET-65 has replaced the ASW torpedo previously carried
Rajput DDG: Styx replaced with Brahmos
NEW DAMAGE SCALING
The damage/armor values for all subs, ships, missiles, and torpedoes has been adjusted. This new scale is meant to correct serious realism errors in DW (e.g., Perry frigates surviving hits from AS-4 Kitchen missiles). The new values are the result of formulas extrapolated from instances of naval weapons use. While by no means perfect (there is a significant amount of variability in real life battle damage, while DW only accepts fixed values), the new values will produce results comparable and consistent with historical engagements and can therefore be considered to be reasonable estimates of typical effects of other weapons. The formulas used are:
Missile Damage= (Explosive damage + Kinetic Energy Damage)* (Flight profile factor) Explosive Damage= (Warhead type Factor)*(1.528*Warhead Mass-.013*Warhead Mass^1.52)
Kinetic Energy Damage= .5(weapon mass*weapon velocity)^2 *.000000102297
Flight Profile Factor= 1 for seaskimmers, .75 for highdivers (abstracted difference in flooding effects)
Warhead Type Factor=1 for penetrating high-explosive, .75 for HEAT, and .33 for fragmentation
In plain English, this means a missile's damage is higher the bigger the warhead (but, with diminishing marginal returns as warhead size increases) and also is higher the more massive and fast the missile is. Hits by seaskimmers do a bit more damage b/c they cause flooding, and sub-optimal warhead types (like on SAMs) get sub-optimal results against warships.
Torpedo/mine Damage= Exlposive Damage * UTK Bonus
Explosive Damage= 3.149*Warhead mass-.0487*Warhead mass^1.55
UTK Bonus= 1.4
At this time, the UTK bonus is implemented only for the 65-76 and underwater mines. This has been done simply to error on the side of making less radical changes. (Note: The mobile mine has been removed from the scale to avoid significant area-damage effects the game engine produces for proximity-detonating weapons.)
In plain English, these numbers mean that the larger the warhead, the greater the damage, but there is a diminishing marginal return as warhead size increases.
Ship/Sub Armor ratings
Armor ratings increase with displacement. Vessels which are not surface combattants have a lower armor value than combattants of equal size.

KILO RETICULE MOD by HITMAN
This mod is included in the 3.09 package as an optional add-on. Separate documentation is included.
KNOWN ISSUES:
The props on some of the new PTGs do not rotate.
The guns on the new PTG's do not have a rotation animation (but they will rotate and fire in the sim normally).
The BrahMos on the Rajput fires to the aft due to the design of the model; in reality, these weapons are forward firing.
The Udaloy II retains the twin gun mounts of the Udaloy I; in reality, a single double-barreled gun system has replaced the twin mounts.
Sub-launched missiles that produce a TIW alert cannot be engaged by the player-controled Perry's CIWS. These weapons include: SUBROCs, Strike missiles, the SS-N-22, and the 1st stage of the SS-N-27 ASM. (All of these weapons are unlikely to be successfully engaged by the CIWS in any case). Sub-launched ASCMs, with the exception of the SS-N-27ASM and SS-N-22, no longer produce TIW alerts.
The Kidd/Chi Teh DDG uses the Tico CG model; some launchers are in the incorrect place.
