Uninspired Sealift vs Cargo 747s vs LCAC Sealift

  1. 1. SEALIFT: CAN IT GET THERE? IN TIME? 25-35 MPH Fast RO/RO Sealift (FSS)
  2. 2. Fast, Shallow-draft “High Speed” Sealift HMAS Jervis Bay type catamaran ferry
  3. 3. HMAS Jervis Bay at Dili, East Timor, 1999 Wakes visible from space when underway HMAS Jervis BayHMAS Jervis Bay Flat-bottom landing craft Break-bulk cargo shipby warf riddledwith debris,guarded by Digger USS BonHomme Richard LHD-6infantryman @ anchor
  4. 4. Unused civilian cargo 747s leased/modified at $10 million each with RO/RO VSramps, 463L pallets as second floor for tracked vehicles can transport: 420-569 troops or 6 x M113A3 Gavins or 21 x Wiesel 2 AFVswww.corazon.com/747specsheet.htmlThe 747-400 can carry more than 57,000 gallons of fuel (215,745 L). Thismakes it possible for the airplane to fly extremely long routes, such asbetween San Francisco and Sydney. The 3,300 gallons (12,490 liters) of fuelcarried in a tank in the horizontal (tail) stabilizer can take the 747-400 anextra 400 miles.8,290 miles @ 500 mph OVER sea mines, submarines, naval blockades,missiles = one-day direct-delivery to TSBEnergy cost: 57, 000 gallons of fuel, If jet fuel is $1 a gallon; $57,000 totalfuel costhttp://biz.yahoo.com/e/000802/luv.html"The average price paid for jet fuel in 2000 was $.7995 per gallon compared to $.4192 in 1999, including the effectsof hedging activities."
  5. 5. Shallow-draft sealift: HMASJervis Bay 86m classcatamaranwww.incat.com.au/incat/pdf/86m.pdfwww.c7f.navy.mil/news/2000/09/16.htmlCosts $66 million each to be purchasedCan carry 569 troops or 15 light armored vehicles1,500 miles @ 45 mph INTO sea mines, submarines, naval blockades,missiles, must offload onto a pier = 1.5 days (33 hours)Uses 125,000 gallons of fuel PER HOUR, only has 33 hour endurance; Fuelcapacity: 4,125,000 gallons Being refueledMust refuel 6 x times (think USS Cole) to get from San Francisco to Sydney, to getAustralia, taking 6 days IF enemy does not interdict. back toEnergy cost: 24,750,000 gallons of fuel Australia from EastDiesel fuel is $1.60 a gallon retail.... Timor...http://www.cunninghamreport.com/TCRmember/archives/TCR/2000-TCR/2000-01-31-TCR-V5N5.htmAssuming the best bulk rate of $1 a gallon, is $24,000,000 for a one-way tripfrom SFO to Australia
  6. 6. If allegedly “High Speed” Sealiftcannot offload because there isno pierside port to offload non-swimming vehicles, then itsspeed becomes ZERO atdelivering combat powerashore... Stryker trucks can’t swim
  7. 7. The answer is to:* Use Cargo 747s to fly TAFV sets* Make vehicles swim: Amphigavinsto offload faster* Use LCACs to get non-swimmingvehicles off existing sealift shipsfaster
  8. 8. Army Pre-positioned Afloat (APA) shipping over-water delivery to avoid sea mines OPTION #1 LO/LO 70-ton crane Pre-po shipEach APA ship has its ownLCAC hovercraft on a sterndeployment “shelf” Tanks/AFVs loaded by cranes into LCACsArmy LCAC with AFVs flies over seamines via air-cushion to deliver groundforces across-the-beach
  9. 9. A low cost option would be to switch a couple slow LCU-2000 landing craft for LCACs on the leased FLO-FLO or put LCACs on T-AKR or T-ACS ships and berth the Navy crews there to operate LCACs fromRRDF barges alongside APS-3 sealift ships. A Float-on/Float-off Ship is a special ship which may besubmerged to allow cargo to be floated on or off, i.e. jack-up platforms and landing craft which may becarried "piggy-back"-fashion on a flo-flo-ship like the MV AMERICAN CORMORANT (T-AK 2062)www.msc.navy.mil/inventory/ships.asp?ship=americancormorant&type=FloFloShipWhile a LCAC can fly over a 4 foot obstacle, its best to have a gradual ramp edge for it to land onto theRRDF barges so the non-swimming vehicles can drive onto the LCAC. The CDI Corporation has donepioneering work developing an Air Cushion Vehicle Landing Platform or ACV-LAP derived from RRDFbarges to get a LCAC interface. The Army has all the parts it needs to configure an ACV-LAP to operatefrom the side RO/RO ramps for LCACs to speed M1/M2s and the other non-swimming ground vehiclesashore at 40+ mph over the water on air cushions. M113A3 Amphigavins would speed themselvesashore from the stern ramp by swimming or helicopter sling-loading. The Amphigavin and ACV-LAPcombination means Army APS-3 forces can offload anywhere in the world despite deep water portavailability or enemy anti-access strategems. FLO-FLO LCAC T-AKR T-ACS ACV-LAP
