Whilemanytechnologicaladvancesoccurinanevolutionarymanner,occasionallyarevolutionarytechnologyappearsonthehorizonthatcreatesstartlingnewconditionsandprofoundchanges.SuchisthecasewiththeprivatelydevelopedMollerSkycar,whichisnamedafteritsinventor.Withtheinventorpermission,Iwouldliketodiscussthemilitarypotentialofthisvehicle.ThereinforcedMollerSkycarvariantthemilitaryisevaluatingiscalledthelightaerialmultipurposevehicle,orLAMV(pronounced"lam-vee").

TheLAMVisaverticaltake-offandlandingaircraftthatcanflyinaquick,quiet,andagilemanner.Itisanewtypeofvehiclethatcombinesthespeedofanairplaneandtheverticaltake-offcapabilityofahelicopterwithsomecharacteristicsofagroundvehicle,butwithoutthelimitationsofanyofthoseexistingmodesoftransportation.

TheLAMVofthefuturewillbe18feetlong,10feetwide,and6feethighandweight2,200pounds.Itwillholdfourpassengersandapayloadof875pounds(includingfuel).Thevehiclewillhaveamaximumrateofclimbof6,400feetperminuteandanoperationalceilingof30,000feet.Itwillattainatopspeedof390milesperhouratanaltitudeof6,000feetandacruisingspeedof350milesperhourat25,000feet,anditwillhaveamaximumrangeof900milesat80passengermilespergallon.TheLAMValsowillbequietenoughtofunctionasanacoustic"stealth"planeat500feet.Itwillhaveaverticaltake-offandlandingcapabilityandemergencyairframe.parachutes,anditwillbecapableofusingvariousfuels.
