Hi to y'all!     
 Since  the vanilla missilies in DCS seem to have a lack in performance  (especially in range), i did a little mod to 'correct' these problems. 
For  the first version of the mod i will only include the NATO weapons  AIM-7M, AIM-120B/C and AIM-9M. Other missiles (air-to-air,  air-to-ground, SAMS and SEAD) will follow (air-to-air shortly). 
I  want to clarify, that all datas used were given by several sources and  show slight variations. Figures given below and used in the mod may  therefore be inaccurate and not completely realistic! 
 The  missile range depends heavily on firing parameters and aircraft radar,  and these numbers are only rough estimates for maximum effective range  in head-on engagements.     
 To be very clear -  even if DCS World is one of the most realistic flight simulations out  there - we will never have 100% realistic flight and weapon behaviour.  The aim of this mod is a better experieence for players. In my opinion  BVR engagements never really happened in DCS because of the lower  missile ranges eagle dynamics implemented. 
Nethertheless  we are talking about approximately 40-60% increase in range for these  air-to-air missiles. Modded missiles were testet with F/A 18C and F-15C  (both client and ai) and worked fine for me (single- and multiplayer). 
 Please  note, that this will significantly change the meta-game in PVE and PVP  environments especially in fights in higher altitudes. Longer attack  ranges and slightly longer flight times also mean more time for the  radar to track counter measures but a bit lesser chance to see the  missiles contrails (obviously).     
 This mod also might affect the balancing implemented by eagle dynamics. 
For  now i did NOT change any flight characteristics other than 'max range',  'missile acceleration', 'rocket motor burning time', 'rocket motor  thrust' and 'max mach'. 
All range data  below refer to the following factors while shooting the missile: plane  h: 10.000 meters V: 900 km/h - the missiles flight characteristics vary  greatly under other circumstances - the lower and slower your plane is  flying, the lesser range you get. 
 First  tests showed that sensors and AI behavior work perfectly with these  changes. Pleas note, that the AI in DCS will not fire at all targets at  max range by default. But you can change these settings in the editor  under 'advanced waypoints' (for testing and scenarios).   
[TABLE]weapon   | vanilla range | modded range | vanilla max mach c.a. | modded max mach c.a.  
AIM-7M   |       50km             |          70km    |           3.2           |           4.0 
AIM-9M   |       11km            |          18km     |           2.7            |           2.7 
AIM-120B |       41km            |          70km    |           4.0            |           4.0 
AIM-120C |       63km            |          100km   |           4.0            |           4.0 
  [/TABLE]I'm very greatfull for any kind of feedback. 
   If you have any credible data about russian missiles characteristics - please send me a link. 
Mod should be JSGME ready.

Sorry for the bad english translation and many thanks to ED for making this awesome sim!   
Best regards and have fun! :pilotfly:
