C&C Attack Helicopter Performance Trials

Note all history is derived from the C&C Roleplay canon.

Overview

The first practical helicopters appeared in the 1930's, and saw limited use in World War II. Liaison aircraft such as the Polikarpov Po-2 and the Piper Cub proved reasonably successful as ground attack aircraft.

By the 1950's helicopters were accepted by various militaries as liaison aircraft, replacing types such as the Po-2 and the Cub. As piston engine gave way to lighter and more powerful turboshaft engines, heavier designs of medium utility could be put forth. Designs such as the UH-2 Trojan and the Ni-2 Baudo Guan were modified into attack helicopters. While moderately successful in counter-insurgency operations, their lack of armor and speed made them vulnerable in high-threat environments. A need for a more heavily armed helicopter gunship was desired.

Review

This is an overall comparison of various types based on role, armament, survivability, and flexibility.

Role:

The primary role of an attack helicopter is close support of ground forces. Many helicopters are dedicated tank-hunters. Given the prevalence of armored vehicles such as tanks in conventional conflicts, this is of importance. However, many sacrifice flexibility against other targets, a factor which is important in unconventional conflicts such as GLA insurgencies.

Dedicated attack helicopters tend to be excellent aerial anti-armor assets, while gunships with passenger accommodations are more suitable for situations where flexibility is paramount.

Armament:

Helicopter armament does not have great variation, often including rotary-barrel machine guns, heavy machine guns, and automatic cannons. Where chin-mounted turret carry any of the variety, some helicopters carry automatic cannons as a fixed armament. Guided anti-tank missiles and unguided rockets are frequently carried. Anti-aircraft missiles can be carried, although SACLOS anti-tank missiles have been employed against slow-flying airplanes and helicopters successfully.

Gunships such as the AHK-100 Jupiter and the MH-2 Trojan possess door gunners. This provides some coverage against soft-skinned or unarmored targets toward the sides. However, the provision is either achieved through the addition of a crew compartment. While a non-issue for gunship conversions such as the MH-2 Trojan, this adds additional bulk to attack helicopters.

Aurelian and Paternian Navy modifications of the Trojan Horse and Shadowhawk, the Berusian AH-20 Enigma, as well as the Korean AHK-99 Renkal and AHK-100 Jupiter possess the ability to mount anti-submarine weaponry. In addition, they can be fitted with equipment such as dipping sonar and in the case of Aurelian and Paternian Navy modifications, magnetic anomaly detectors. In this case, the Trojan Horse and Shadowhawk are superior; while the Korean and Berusian helicopters are faster, their anti-submarine armament is comparable to the Aurelian/Paternian helicopters, and the significant armor protection offered is irrelevant in anti-submarine operations. The greater simplicity of the Aurelian/Paternian helicopters mean that higher readiness and greater numbers of sorties can be launched.

Questionable is the capability to deploy tactical nuclear weapons on the AH-20 Enigma and AHK-99 Renkal. The capability of employing such weapons are risky with the inherently low speed compared to other delivery platforms, as well as political ramifications of employing nuclear weapons of any yield. As it is widely regarded as taboo to employ nuclear weapons of any size from any platform against any target, the risk to benefits ratio is incredibly poor. While the risk-benefits ratio of nuclear weapons employment is always poor, larger weapons for use against strategic targets are considered more worthy of such risks than tactical targets.

Furthermore, due to these incredible risks, nuclear weapons are generally strategic-level weapons under the control of high-ranking civilian authorities who understand the risks of employing such weapons. Tactical-level nuclear weapons under the control of a military officer trained to take high risks are seen as a significant risk liability, and thus is not employed commonly, if at all. Thus, the expense of allowing such helicopters to deploy tactical nuclear weapons is to the opinion of the evaluation editor, superfluous.

Survivability:

There are five factors which determine the survivability of a helicopter: performance, armor, size, countermeasures, and component redundancy.

Dedicated attack helicopters tend to fare better in this regard than gunship conversions of transport or scout helicopters due to their higher performance, superior armor, smaller size, integrated countermeasures, and integrated component redundancy. An exception to this is the MH-65 Shadowhawk, which features comparable performance, integrated countermeasures, and integrated component redundancy. In some of these regards, it is superior to dedicated platforms.

The compound helicopters (i.e. the AHK-99 and AH-20) are the best at avoiding fire with speed and maneuverability, the AHK-99 being slightly more maneuverable, but the AH-20 being somewhat faster. Scout helicopters, notably the OAH-3 Scout tend to be somewhat slower but more maneuverable.

As armoring goes, all dedicated attack helicopters can resist fire up to 12.7mm, and heavier in some places. Dedicated anti-armor helicopters tend to have greater armor protection than others. Gunship conversions of utility or scout helicopters often lack in this regard.

As for countermeasures, the situation remains as dire for the utility and scout helicopters. This is especially true for older machines such as the MH-2 and AH-2. However, both are capable of accepting such systems.

Size is another consideration, mostly the frontal profile. Converted utility and scout helicopters with their side by side seating present a wider target for ground fire than if the helicopter had a front and back arrangement. Thus, dedicated attack helicopters tend to do well in this regard.

Converted scout helicopters such as the OAH-3 Scout, while possessing a side-by-side arrangement, are fairly small machines and present a small overall profile.

However, component redundancy, especially in engines, are a universal feature, as they offer greater survivability in exchange for bulk. Virtually all current helicopters have two engines for this reason. Notable exceptions are the AHK-99 Renkal and OAH-3 Scout, whose lightweight designs mandate single-engine operation.

Older helicopters such as the H-2 series (Trojan Horse and Spartan) lack this capability. However, upgrades have compensated for this deficiency.

While the AHK-99 Renkal and AH-20 Enigma are very fast, well-armored helicopters, their mechanical complexity and in the case of the Renkal, single-engine design makes it vulnerable to ground fire. The MH-65 Shadowhawk and MH-2 Trojan Horse with the Gemini upgrade, while possessing twin engines and some redundancy, lack any armor, size, or significant mobility advantage that would allow it to avoid fire.

Special mention must go to the HA-121 Albatross. While well-armored, well-armed, and brimming with countermeasures, it lacks redundancy, and more importantly, mobility. With a maximum speed of 82 miles per hour, it is far too slow to be survivable.

Flexibility:

Of the evaluated helicopters, the Paternian gunship conversions are easily the most flexible. Almost all of them, with the exception of the AH-2 and the AH-58, are conversions of existing scout or utility helicopters. Even the AH-2 retains significant parts commonality with the UH-2 and MH-2.

These helicopters can be converted into attack helicopters with nothing more than a simple kit and a 1" socket wrench. They retain all of their transport abilities in such a modification, and can be used to carry troops, material, and casualties. If necessary, the kits can be removed and the aircraft returned to use as a pure transport with sling loads.

A notable exception is the AHK-100 Jupiter. Capable of carrying 9 soldiers inside the cargo compartment, it possesses many features reminiscent of attack helicopters. It is thus the only design mentioned which can come close to the versatility of gunship modifications.

Conclusions

Attack helicopters are built to the priorities of the forces which procure them. Korean, Lanzarrian, Berusian, Soviet, and some Paternian machines are potent anti-armor weapons platforms, but are either too expensive or too specialized for other tasks. Most Paternian machines are reasonably flexible transport gunships, trading firepower for utility.

Compound helicopters are excellent tank hunters with their speed and weaponry, but fare badly against ground fire. More traditional helicopters are more flexible, but slower.

Which helicopter is best is entirely dependent on your needs. Take a look at the list and see which ones fit your needs the best.
