Report 011: Guided bombs in all flavors


In the last week, following addition of the guided bomb system only a few actual
weapons were made available.
Considering the wide variety of roles and characteristics these weapons can have, that list was too small and limited. Therefore, to offer a wider selection this week was focused on expanding the collection of guided bombs, so that our pilots will be able to choose the best weapon for any particular situation.

Another issue was pointed out from our pilots, was that only a few of the available aircraft could use guided bombs.
Our base already requested a new aircraft and it should be delivered in the next weeks. But before that, to mitigate the issue of few guided bomb users, a solution appeared: a modernization plan for the su-27S.

The Su-27SM:

Although visually very similar to the S version, it can be distinguished by offset IRST ball in front of the cockpit, the addition of the refueling probe and the ECCM in the leading edge of the wings.

But the biggest difference it is in the performance, as it is one of the most technological advanced fighters in the su-27 family and one of the most effective aircrafts in the whole 4th generation of fighter aircrafts.


This modernization improves greatly the avionics and radar performance. Increasing it combat effectiveness it also add the compatibility of high-precision weapons.

In game shot of the Su-27SM:

The MiG-21 will follow this modernization to also support guided bombs.

Before showing the newly added weapons, a simple explanation about the differences in some warheads and guidance systems.

Some types of warheads:

High explosion 
The most conventional type of warhead is the high explosive, commonly referred to simply as HE.

 Good coverage area
 Excellent for carpet bombing
 Weak against shelters

Piercing 
Armor piercing is a type of warhead made to penetrate hardened targets. In case of bombs they are known as “bunker busters”, as they explode below ground destroying the foundations of any structure.

 Excellent against high value targets and reinforced structures
 Excellent against ships and submarines
 Narrow blast range

Thermobaric 
Result of a quick disperse an aerosol cloud of fuel which is ignited by an embedded detonator to produce an explosion. The rapidly expanding wave front due to overpressure flattens all objects within close proximity of the epicenter of the aerosol fuel cloud, and produces debilitating damage well beyond the flattened area. The main destructive force of Thermobaric explosion is high overpressure, useful against soft targets such as minefields, armored vehicles, aircraft parked in the open.

Also known as fuel-air bomb and it is the type of warhead used for the two most powerful non-nuclear bombs, the MOAB and FOAB.

 Extremely large coverage area
 Powerful weapon against soft skin units
 Weak against reinforced structures

Incendiary (Note: this type of warhead it is not available yet)
Often referred as Napalm, the incendiary bombs use chemical reactions to spread fires. These bombs, if dropped in the right conditions they can cause a long line of fire

 Good against unarmored units or personal
 Good against convoys
 Causes persistent damage
 For maximum efficiency requires to be dropped in certain conditions
 Useless against shelters or reinforced structures

Cluster (Note: this type of warhead it is not available yet)
This type of warhead it is unique, it main role it isn’t to damage the target, but instead is to spread smaller sub-munitions carried inside of the projectile. Then these sub-munitions will damage targets in a wide area.

 Good for bomb saturation
 Good against armoured vehicles
 Must be dropped from altitude to have good coverage area
 Some clusters have random dispersion of sub munitions

(Note: it is possible to mix the characteristics of various warheads)

Some types of guidance system:
TV 
The TV guidance system uses the fire-and-forget principle as the weapon guides itself to the target, however to be effective, it must be deployed in daylight and clear conditions.

 Can be Remote controlled.
 Fire-and-Forget.
 Limited to daylight.
 Limited to clear weather.

(Note, in the future, the player will have the possibility to remote control some TV guided weapons)

Laser
The Laser guided is the most common and the most versatile guidance system for bombs; it can be deployed day or night. One drawback of this kind of guidance is that the aircraft must continually “paint” the target and therefore to ensure accuracy can’t take evasive maneuvers if targeted by enemy fire.
In case of the signal loss, the projectile goes ballistic.

 Works in all lighting conditions
 Stays effective against stealth units
 The aircraft must be able to paint the target avoiding the interference of obstacles
 Loses effectiveness in bad weather
 Laser illumination can be interrupted by smoke, fog, or clouds
 Aircraft venerable when using this weapon

(Note, in the future, tanks can take evasive measures creating a smoke screen in an attempt to disrupt the laser guidance)

(Note 2, in the gameplay perspective, the target must stay locked for the weapon to be able to aim properly)

IIR
The Imaging Infrared, often called as “heat-seekers”, is like the TV guidance, it can also maneuver independently to the target without any further input from the aircraft. Unlike laser-guided bombs which can only be employed in clear air-mass conditions, the IIR is able to achieve accuracy in adverse weather.

 Fire-and-Forget
 Works in all lighting conditions
 Usable in all weather
 Ineffective against cold bodies
 The existence of a variety of infrared countermeasures.

Sat Nav 
The Satellite guided weapons are able to operate in all weather and lighting conditions. In comparison with other guidance systems, it has the upper hand against countermeasures.

 Fire-and-Forget
 Works in all lighting conditions
 Immune to countermeasures
 Usually fixed positions
 Must be able establish connection with a navigation satellite

(Note: an effort is constantly being made for the game to be as accurate as possible in specs, loadouts, etc. However the user is free to change or simplify the configurations as he likes when moding the game)

Now the weapons:


Guidance: TV

Warhead: HE

Smart bomb KAB-500S-E with satellite guidance and HE warhead is a high-precision fire-and-forget aircraft weapon.

The KAB-1500S-E is a satellite aided inertial guided bomb. It to uses the same guidance package as the smaller KAB-500S-E but has more powerful blast.

Currently for:
Su-27SM
Su-47


Guidance: Radar/Sat Nav
Warhead: Thermobaric

The last one it is not a bomb, but instead a missile, created to test the versatility of the warheads in current system.
It is long-range ballistic missile developed to be a multi-purpose weapon, destroying both air and ground units with a huge air Burst.
In theory is a very devastating weapon combining the fuel air explosions with other high explosives, resulting in something similar to a small thermonuclear bomb.
However, to this date there is no actual data of the missile performance, the use of this weapon would draw too much attention from our enemies, so to avoid that it will be stored in a safe place in case of a future use.

Currently for:
None

(Note: By the default this weapon it is not available for any aircraft and is “hidden” in the game data. To be able to use this weapon, the player must include it in an aircraft’s default list of weapons.)

With this new pack of weapons, most of the relevant guided bombs are now available. So in the future, the inclusion of other guided bombs will be reduced and upcoming additions will be focused on other types of weapons.

  • Added Speed State animations (now the flaps an trims can move properly and it is also possible to have aircrafts with variable wing geometry)
  • Added velocity dependent animations

  • Added Su-27SM aircraft
  • Added GBU-15(V)/1B weapon
  • Added GBU-15(V)/2B weapon

  1. Is it me or I feel that termobaric is a typo? (should be thermobaric IMO) :\

    BTW, nice job at putting ACZ’s MPBM

  2. A bit OOT, from what I’ve get, in ACZ-verse the MPBM isn’t using FAE warhead. it uses polynitrogen as its main component.

  3. A stupid question: Will the flight engine supports prop planes? :3

    • It is not a stupid question at all! But by now, it is already fully supports prop planes.
      Gradually it’s becoming even more flexible, so in the future it will be possible to add organic models. (for a dragon rider mod maybe?)

  4. I think…

    ugh, Touhou mod is already inevitable? :\
