There were worrisome reports in the media yesterday saying the landing craft on the Royal Australian Navy’s Landing Helicopter Dock ships, HMAS Canberra and HMAS Adelaide, are not capable of delivering M1 Abrams tanks from ship to shore using their own landing craft.

It seems the LHD landing craft (LLC) (which were bought after the original landing craft they replaced were found to be incapable before they even entered service), can carry a max load of 65 tonnes in ‘benign sea conditions’ – and their safe carrying capacity is progressively reduced to just 39 tonnes in sea state 4.
Or at least that was the theory.
Now it seems the RAN has suspended M1 Abrams tank-delivery trials using LLCs because the landing craft “sat lower in the water than expected” when a tank was driven onto them.
By the way, the current in-service M1 Abrams tank weighs 62 tonnes – which means that even if the landing craft performed as advertised, they could only deliver the Army’s main battle tank to the beachhead if the water was dead calm.
But now it seems they can’t even do that.
And, compounding this dilemma, future upgraded M1A2 Abrams tanks, which the Australian Army is already contemplating, could weigh up to 72 tonnes – which means LHD delivery will be a no go regardless – unless HMAS Choules and her mexeflote barges are nearby.

Mexeflote【120頓的登陸艇】 only for Abrams as LCM trial suspended，
Patrick Durrant | Sydney Navy has responded to questions it took on notice during the May Budget Senate Estimates hearing, revealing trials it was conducting to test the suitability of the LHDs’ landing craft for carriage of Army’s main battle tank, the M1A1 Abrams, have been suspended The tabled answer to Senator Gallacher’s numerous questions on the topic stated that the trial was suspended because the LCM-1E landing craft “sat lower in the water than was predicted”【下沉太多】 when the 57 tonne MBT was embarked下水時.
The maximum load carriage capacity of the LCM-1E in benign weather conditions is 65 tonnes, decreasing to 38.9 tonnes in Sea State 4 (moderate, wave height from 1.25 to 2.5 metres).
Interestingly, Navy stated further test and evaluation activities may change these figures.

Tonne for tonne, ST Marine's Endurance 140 design can carry more landing craft than any other LST/LPD design available today. The mothership can land a battalion-size team【我估是幾佰人】 in one wave using its onboard FCUs and Fast Craft Equipment Personnel (FCEP) landing craft.
