Weapons
AIM-54
The AIM-54 will be the most used A/A weapon for the F14 and is unique to this aircraft. It is a long range actively guided A/A missile. It was originally meant to be deployed on the F111B to intercept bombers and cruise missiles at very long range. Additionally, learning from the Vietnam conflict, the missile also had to be able to engage maneuverable fighter aircraft at medium ranges with high hit rates. This led to a missile which in testing achieved a max range shot of ~115nm and was the first missile to hit a target pulling more than 6g's successfully.
(note this next part is WIP as of 7/14/2019 as we are waiting for HB to get access to a working missile API but once they do the AIM-54 will behave as described in the following text. Until then it acts essentially like an AMRAAM)
Due to the more antiquated nature of its electronics the 54 does have downsides to its deployment. First, it is not truly fire and forget in TWS mode like the AMRAAM is. The computer has to tell the missile to go active via a RF pulse sent through the missiles datalink. This is often commanded 16sec before impact. Tactically speaking this means a turn too far away from the target will result in the missile not receiving the pitbull command. This can be averted if the pilot flips up the ACM cover (missile is active off the rail) or if fired in STT where the missile will guide PD like a big Sparrow.
On the other hand when using STT the missile will go into a SARH mode. While operating in SARH mode if the STT lock is lost the missile will not go active and an STT lock must be reestablished. Additionally, while in a Pulse STT lock the missile will not be able to loft and will not receive the range befit this mechanism provides.
There are 3 main types of AIM-54:
| A-47 | A-60 | C-47 |

*From HB http://media.heatblur.se/AIM-54.pdf
AIM-7
The Sparrow III is the third major revision of the venerable sparrow design of the early 1950's. It was the frontline BVR A/A missile for the United States Airforce, Marine Core, and Navy until the early to mid 1990's; ultimately being replaced by the AIM-120 series of missiles. The sparrow III, when compared to its predecessors, is a significant improvement in every way, it features a design that was easily upgradable over time. The ultimate version we have in DCS the MH variant features lofting logic and improved CCM performance over previous models.
F
The first Sparrow variant fielded of the new type the F sets the aerodynamics and range for all futures sparrows. Unique to this variant is the ability to home in on either a CW signal or a PD signal. Even though not implemented on the F14 yet, in the future you should be able to choose between the two modes. This in game means all three types of sparrow perform kinematically the same, however the F's chaff resistance is extremely low and can be decoyed with only a few chaff bundles.
M
The upgrade to the F-model, the M build irl received a new, and substantially better, monopulse seeker and a choice between two nose cones. One optimized for radar performance the other for aerodynamic performance. The monopulse seeker gives this missiles an inherent resistance to chaff and ECM. However this means it can only home in on a PD signall. In game the only difference from the F is a substantially improved chaff resistance.
MH
The MH variant is the most modern sparrow currently in DCS. This variant uses parts from the AIM-7P to improve its long range performance with lofting and low altitude performance with newer guidance computers. Additionally, the CCM logic was upgraded substantially. In game this makes the MH the most effective variant due to its lofting and CCM performance making chaff have a very low effectiveness against it.
AIM-9
The Sidewinder is the longest serving missile series in the world. It has seen massive improvements over the more than 50 years it has been in service. The F14 can currently carry two types the AIM-9L and the AIM-9M
L
The '9L' was the first of the "unified" Sidewinder models, as previously the Airforce and Navy had their own unique model, this one was the first to be used by both branches. The L was a major upgrade over all previous sidewinders, heavily based on the AIM-9H the ultimate navy only variant. The L featured a new cooled InSb (Indium Antimonide) FM spin seeker which provides some natural resistance to IR counter measures, a completely new electronics package, increased off boresight capabilities, higher max G, higher launch g (7g's), much longer flight time of 1 minute, New warhead, new and more powerful motor.
M
The '9M' in shape, size, weight, and even appearance is the same missile. But on the inside its electronics got completely overhauled. These new electronics could now filter out flares based on a flares energy rise time. And be reprogrammed to keep it up to date with the latest threats.
In addition these updates almost completely eliminated the effect of background noise on target detection range. In addition to this the 9M got a new smokeless motor that almost completely removed the smoke signature of the missile.

- Half press - Half action (Home) - used to allow slewing of TID selection cursor and DDD selection cursor
- Full Press - Full action (PgUp) - Used to select a target or object on the TID and engage a lock with the DDD.
- Operating mode buttons, in order from top to bottom:
- IR/TV HCU takes manual control of IR/TV camera slew and elevation control
- RDR - HCU takes control of the radar antenna azimuth and elevation to perform lock on using the DDD in PD, Pulse, or RWS.
- DDD Cursor - Used to mark a geographical location in Pulse mode for a NAV system update or to mark ships on the DDD
- TID Cursor - HCU takes control of the TID cursor allowing it to 'hook' targets for either lock on (TWS) or moving of waypoints/creation of waypoints
Displays:
TID - "Tactical Information Display"
This is one of the AWG-9's radar displays. This screen will be the one you use the most as the RIO as it provides the largest picture of the battlespace. The scale of the page is set by a control nob near the HCU (Hand Control Unit) that we will look at more latter. With the options of 25,50,100,200,400 Nautical Miles scales.
To the Left of this nob is the display mode nob.
- GND STAB - Centers ownship in center of screen with up being true north. Scale is the Diameter of the screen.
- A/C STAB - Normal display mode, aircraft heading is straight up on the display.
- ATTK - Adds attack steering symbology such as DLZ and the max launch error circle.
- TV - The TID will display the TV image from the nose mounted camera or the lighting pod image.
The Display items add and remove items that are displayed on the TID. Going from Left to Right:
- RID Disable - Not in use
- ALT NUM - Shows or hides the Altitude numbers
- SYM ELEM - Symbology elements, enables or disables the showing of waypoints and tracks. Contacts will appear only as a small dot
- DATA LINK - Enables or disables the display of Datalinked tracks
- JAM STROBE - Enables or disables the display of Jammer Strobes
- NON-ATTK - Enables or disables the display of targets that are beyond RMAX for your current missile. Additionally non-attackable targets such as friendlies will be added/removed
- VEL VECTOR - Enables or disables the display of the velocity vector.
- LAUNCH ZONE - "Enables display of weapon launch zones depending on selected missile type. These replace the velocity vectors on relevant targets. This function is automatically enabled by the WCS 60 seconds prior to a target entering maximum launch range."
On the main screen itself there are quite a few different symbols. On the left is the radar elevation 'box', the top row is the upper elevation limit of the scan pattern. The middle is the current radar elevation in degrees. And the bottom line is the lower scan volume limit. On the right side of the screen you can see closing velocity, weapon selected, and number reaming. In the center of the screen the dashed lines extending out from your ownship symbol are the radar scan azimuth limits. Each dash, and space in between, is exactly 20NMi's long and will scale to your current range setting. At the top of the display, when a contact is 'hooked' it will alternate between displaying the targets LAT/LON and its range and Relative bearing left or right to your centerline. With the name of the target shown in the box above the TID screen.
http://www.heatblur.se/F-14Manual/general.html#tid-symbology
Ownship contacts:
Each radar contact that has been processed will appear as a dot with a HAFU (identification) symbol above them. If the RIO is in either PD or Pulse no contacts will be displayed. In the main TID image the contact shown has been marked as hostile. The altitude is shown to be 2 which translates to an altitude between 15 and 25 thousand feet. With a closing velocity of 1052Kts directly at the ownship. A HAFU symbol can be changed manually by selecting the contact with the HCU. First press half action to get the cursor then when hovering over the target press full action to 'hook' the target. Then in the TGT Data CAP page one can manually update the targets identification.
Datalink contacts:
If one has ether a LINK4A or 4B datalink operating the TID will display tracks from off board sensors. These will appear as a normal contact with a HAFU below the center dot. If your radar also sees this target it will form a complete box, diamond, or circle. In addition to contracts waypoints can be sent as well.
DDD - 'Detail Data Display Panel'
This is one of the AWG-9's radar displays. This display is used to show a more raw unprocessed radar picture than what the processed image which is shown on the TID. This display in PD and RWS and TWS shows data in terms of azimuth vs rate. Meaning the X-axis is the azimuth from your aircraft and the Y-axis is the closer velocity. Additionally this rate is not the relative closing velocity like what you may see on a HUD for a modern aircraft but it instead subtracts out your ownship velocity, or the observed closer rate observed against the ground. This is done because if it wasn't you'd only get an accurate closer reading for in a direct line right in-front of your radar.
The above image indicates the display in PD mode. Keep note the scale can be changed with the X4 switch to the right of the DDD display:
If set to NORM then scale is -200Kts to 800Kts
If set to X4 the scale is -800kts to 4000kts closing, good for large missiles such as the P800.
Radar Modes:
PD
- Longest range mode, uses just a PD signal without the FM ranging method. This can provide target detection well in excess of 100NMi for large bombers and tight groups of smaller targets; and just in excess of 100NMi for most other targets. Does not provide ranging information only closing velocity and azimuth on the DDD only.
RWS
- Second Longest range mode, uses a PD signal with FM (frequency modulation) ranging techniques. This provides detection of large targets, or tight formations of several smaller targets, at ranges just over 100Nmi. Provides ranging, elevation, azimuth, and closing velocity information.
TWS Auto
- Track while scan - A search mode that dedicates part of its search to momentary tracking of a target to provide more detailed elevation and target heading information. In TWS AUTO the computer will seek to keep as many targets in the scan volume as possible. When a missile is fired the fired upon target will be centered in the scan volume. If a second target is shot at the computer will seek to keep both targets in the scan volume. The center of the scan, when viewed from above, will be shown by an X symbol on the TID.
TWS Manual
- Track while scan - A search mode that dedicates part of its search to momentary tracking of a target to provide more detailed elevation and target heading information. In TWS manual the RIO controls the location of the search volume in both elevation and azimuth.
Pulse
- The shortest range radar mode, this mode searches with a Pulsed radar signal instead of a PD signal. This mode is limited in many aspects, it cannot detect closing velocity due to a lack of its ability to detect a doppler shift. Additionally this mode is susceptible to ground clutter, chaff (not yet implemented), and jamming due to a lack of a MTI filter or Doppler filtering. This mode, however, has no notch making it useful in locking up flanking targets. And as a rudimentary A/G radar for locking up ships at sea. However due to the lack of filtering you will see ground returns on the scope and picking targets out from this is a skill that will only come by practice. The Pulsed radar returns are only showed on the DDD with the range scale being set with the row of buttons above the DDD.

Close in Radar modes
The piolt normally doesn't have any control over the radar but for ACM he can take over the radar and put it into a few different modes:
PLM
A boresight mode the radar will lock any targets within a few degrees of the gun cross within 5Nmi
PAL
A large horizontal scan mode the radar will lock anything within 15Nmi's
VSL Hi|Low
A vertical scan mode the radar will scan and lock a target in a small vertical section centered at the gun cross.
A/A Setup
1) Set HUD to A/A mode
2) ()
3) Master Arm to cover up and switch up.
4) Select Weapon
