I thought you were some kind of retired army man, and thus assumed you would understand amphibious warfare beyond Rambo movies. If we go by your analysis, then amphibious warfare is obsolete and countries like, the US, Britain, France, China etc with large amphibious forces are wasting their time then.
Hovercraft do not just float into contested territory with infantry on board all Rambo-like Ray, its called air-superiority and SEAD/DEAD. Both must be undertaken and achieved before any amphibious force in the world, including the USMC and Royal Marines can land on a beach and establish a beach head.
That's why any large amphibious operation is usually undertaken under the air-defense umbrella of a CBG, as seen in the recent joint Anglo-French Corsican Lion excercisse where MN Mistral class LHD's and RN Albion Class LPD's(quite similar in tonnage and capacity to the Type 071 LPD) delivered hundreds of troops and multitudes of armor and other military support vehicles on to a beach head under the umbrella of the MN carrier Charles De Gaulle's flight operations.
Only after
1. the air-space has been cleared of enemy flight operations,
2. SAM installations have been detected and destroyed
3. and airborne infantry( either dropped by fixed wing air-lifters or via heli-borne assault) and helicopter gunships have cleared the beach head of enemy armor and anti-tank weaponry bearing infantry,
do sea-borne amphibious operations(including all ship to shore connectors - eg. hovercraft landing craft, catamarans(MN's case), logistics helicopters etc ) begin.
In the Corsican Lion excercise, Rafale and Super Etendard fighter aircraft both cleared the air-space and performed DEAD operations against land targets with the assistance of E2C AEW&C aircraft and Tigr helicopter gunships.
AAW ships clear the sea-space of enemy aircraft and naval vessels as well as provide AA cover for ASW operations to remove sub surface threats such as lingering coastal SSK's.
Tigr and Apache gunships also cleared the beach head of infantry and armor formations as well as denying the immediate sea space to small boat operations by the stimulated opposition. Then a helicopter assault involving NH90, Super Puma, Merlin as well as Chinook transport and utility helicopters transported marines and their logistics support over to the beach head under the protection of Apache, Tigre and Lynx/Lynx wildcat anti-armor and anti-personel flight operations over the beach-head and surrounding battle space.
Only then did the new MN ship-to-shore connector catamarans, landing craft and RN landing craft deliver their cargo from their amphibious, well deck equipped mother ships: FNS Mistral, HMS Bulwark, and RFA Mount's Bay.
A major amphibious operations undertaking isn't just a single LPD carrying hovercrafts and two or three heli's trying to establish a beach head on its own. It's an enormous undertaking involving several naval capital ships and their various support vessels, all performing their design capabilities towards the establishment of a beach-head on enemy or contested territory..,
I know you'll say you knew all this, but I'm posting it alll anyway.
PS. Amphibious warfare isn't carried out in heavy sea states anyway because heavily laden soldiers would drown should their landing craft capsize or be sunk as they make their way to land.
Hovercraft are also much more sea worthy in heavy sea states because of their natural buoyancy vs their more traditional landing craft cousins. Both the PLAN/PLAMC and USN/USMC aren't idiots for choosing hovercraft over the basically WW2 technology landing craft you know... But maybe you're smarter than both these massive organizations
,
As anyone would know amphibious warfare can never be out. Therefore, your contention that I have suggested so is totally bogus and deflectory. It is just that the composition of the force will vary depending upon the task and phases of the operation. All countries that have island territories or desire expeditionary forces, will have amphibian capability.
The issue is that is being debated is the usefulness or otherwise of Hovercrafts in such operations.
It is easier said than done that there will be air superiority, SEAD/DEAD unless ofcourse one is contesting very weak countries like Iraq vs US. Integrated Air Defence continues to be a deterrent and to believe that it will be a cakewalk with SEAD/DEAD is living in a Fool's Paradise. If it were not so, none would be pouring billions on research into Stealth Technology. Also one must should remember that engagement and acquisition radars are automatic pseudorandom frequency hoppers, many in fact "fast" frequency hoppers with pulse-to-pulse hopping capability and they can defeat offensive measures taken against them. These radars is currently in use with even the Chinese military.
Attempting to project yourself as a military expert your own statement gives away that you do not understand warfare
You stated:
large amphibious operation is usually undertaken"¦...only after"¦"¦..airborne infantry( either dropped by fixed wing air-lifters or via heli-borne assault) and helicopter gunships have cleared the beach head of enemy armor and anti-tank weaponry bearing infantry,
Now, if AB infantry and other forces have cleared the beach of armour and infantry, where is the need for amphibious warfare? The beach having been cleared of the enemy would mean the beach head has been established and the expeditionary force can safely land.
I might draw attention to use of Hovercrafts in combat. In the Gulf War, Assault Craft Unit 5 equipped with LCACs were used. But they were used to merely ferry men and materiel not under active combat conditions.
To obviate wishful pithy patter, let us see what the US (possibly the only nation that can independently mount expeditionary force, has to say.
An
amphibious operation is a military operation launched from the sea by an amphibious force, embarked in ships or craft with the
primary purpose of introducing a landing force (LF) ashore to accomplish the assigned mission.
Types of amphibious operations include assaults, withdrawals, demonstrations, raids, and other operations in a permissive, uncertain, or hostile environment.
Comprise the initial phase of a campaign or major operation where the
objective is to establish a military lodgement to support subsequent phases.
Types of Amphibious operations are:
Amphibious Assault. The establishment of an LF on a hostile or potentially hostile shore.
Amphibious Withdrawal. The extraction of forces by sea in ships or craft from a hostile or potentially hostile shore.
Amphibious Demonstration. A show of force conducted to deceive with the expectation of deluding the enemy into a course of action unfavourable to it. (
This was done in Gulf War I)
Amphibious Raid. A swift incursion into, or a temporary occupation of, an objective, followed by a planned withdrawal.
Other Amphibious Operations. The capabilities of amphibious forces may be especially suited to conduct other types of operations, such as noncombatant evacuation operations and foreign humanitarian assistance.
The
characteristics of an amphibious operation are:
Integration between the Navy and landing forces. The key characteristic of an amphibious operation is close coordination and cooperation between the ATF, LF, and other designated forces.
Rapid buildup of combat power from the sea to shore. The salient requirement of an amphibious assault is the necessity for swift, uninterrupted buildup of sufficient combat power ashore from an initial zero capability to full coordinated striking power as the attack progresses toward amphibious force objectives.
Task-organized forces, capable of multiple missions across the full range of military operations to enable joint, allied, and coalition operations. Amphibious forces are task-organized based on the mission.
Unity of Effort and Operational Coherence. The complexity of amphibious operations and the vulnerability of forces engaged in amphibious operations require an exceptional degree of unity of effort and operational coherence
Unity of Effort and Operational Coherence. The complexity of amphibious operations and the vulnerability of forces engaged in amphibious operations require an exceptional degree of unity of effort and operational coherence.
What constitutes an amphibious operation?
The following constitutes an amphibious operation.
Amphibious Assault. An
amphibious assault involves the establishment of an LF on a hostile or potentially hostile shore. The organic capabilities of amphibious forces, including fire support, logistics, and mobility, allow the United States to gain access to a crisis area by forcible entry.
Forcible entry operations can be accomplished through amphibious operations, airborne operations, air assault operations, or a combination of any or all of these forcible entry techniques. If the JFC's decision is to use a combination of forcible entry techniques to seize a lodgement, the JFC must further decide, based on maritime factors and mission, enemy, terrain and weather, troops and support available, time available analysis, whether to conduct the forcible entries as concurrent or integrated.
Concurrent forcible entry operations occur when a combination of amphibious, airborne, and/or air assault forcible entry operations are conducted simultaneously, but as distinct operations with eparate operational areas and objectives.
Integrated forcible entry operations result when amphibious, airborne, and/or air assault forcible entries are conducted simultaneously within the same operational area and with objectives that are mutually supporting.
I might add that
Amphibious Operation should not be mistaken for Forcible Entry Operations. It may constitute to be an element of a Forcible Entry Operation
LCAC's construction is soft skinned and has no armour protecting the crew or the troops. It is a large craft and hence a large radar reflection. Once on land, its speed and manoeuvrability, it is reported reduces to 6 knots. Its six gas turbines are very noisy and can be heard from great distances. If damaged LCACs are difficult to tow and driving in reverse is taxing to the driver. It is said that it has a large turnaround time.
Now given the above, do fit Hovercrafts in an amphibious operation in the active combat role in an amphibious landing.
