Kungani i-JDAM inenzuzo kangaka?
Context:I-Joint Direct Attack Munition (i-JDAM) iyisethi yokuqondisa eguqula amabhomu angaqondisiwe, noma "amabhomu ayiziphukuphuku", abe yizikhali eziqondiswa ngokunemba kuzo zonke izimo zezulu. Amabhomu ane-JDAM aqondiswa uhlelo lokuqondisa oluhlanganisiwe oluhlanganiswe nesamukeli se-Global Positioning System (GPS), esinikeza ibanga elishicilelwe elifinyelela kumamayela ayi-15 olwandle (28 km). Amabhomu ane-JDAM asukela kumakhilogremu angu-230 kuya kwangu-910. Uhlelo lokuqondisa lwe-JDAM lwakhiwa ngokuhlanganyela yi-United States Air Force kanye ne-United States Navy, yingakho "okuhlangene" ku-JDAM. Lapho ifakwe ebhombeni, ikhithi ye-JDAM inikezwa i-GBU (Guided Bomb Unit) yokuhlonza, ithatha indawo yeMark 80 noma i-BLU (Bomb, Live Unit) yokuqamba ibhomu elixhunywe kuyo.  I-JDAM ayisiyona isikhali esizimele; kunalokho iyiphakethe lokuqondisa "elihlanganisiwe" eliguqula amabhomu adonsela phansi angaqondiswa abe yizikhali eziqondiswa ngokunemba (PGMs). Izingxenye ezisemqoka zohlelo zihlanganisa ingxenye yomsila enezindawo zokulawula i-aerodynamic, i-strake kit (body), kanye nesistimu yokuqondisa i-inertia ehlanganisiwe kanye neyunithi yokulawula ukuqondisa i-GPS.  I-JDAM yayihloselwe ukuthuthukisa ibhomu eliqondiswa nge-laser kanye nobuchwepheshe bokuthwebula izithombe nge-infrared, obungaphazanyiswa isimo esibi sezulu nesomhlaba. Manje sekufakwa ama-laser seekers kwamanye ama-JDAM.
I-Joint Direct Attack Munition (i-JDAM) iyisethi yokuqondisa eguqula amabhomu angaqondisiwe abe yizikhali eziqondiswa ngokunemba. Kunezizathu eziningana zokuthi kungani i-JDAM ingenye yezikhali ezibiza kakhulu ezake zasungulwa.  Ngokusebenzisa i-GPS navigation, ikhithi yokuqondisa i-JDAM ingaba eshibhile kakhulu, ibe ngaphansi kuka-$25k/kit. Cishe ishibhile kunanoma yiziphi ezinye izikhali eziqondiswa ngokunembile.  Ukuzulazula nge-GPS kunikeza ukunemba okuhle kokukhomba, ngokuvamile ngamamitha. Uma ihlanganiswa namabhomu angenakuqondiswa anobubanzi obuyi-500 kuya ku-2000 lbs, i-JDAM ingakwazi ukubhubhisa noma imiphi imigomo esemhlabeni.  Ngenxa yokuthi i-JDAM inekhono lokuzulazula, abashayeli bezindiza abasadingi ukuqondisa ngokunembile amabhomu ngokumelene nemigomo. Ivumela ibhomu ukuba lisheshe futhi lishaye ngokunembile izinhloso eziningi endleleni.  Amanye amakhithi okuqondisa ama-JDAM ahlanganisa izinzwa zokukhomba, njengokukhomba i-laser. Zingasetshenziswa ngokumelene nemigomo ehambayo, okwandisa kakhulu amacala okusetshenziswa kwe-JDAM.  Ngamafuphi, ngokuhlanganisa amabhomu angasho lutho nekhithi yokuqondisa, i-JDAM iba uhlelo lwezikhali olubiza kakhulu, futhi lwamukelwa kabanzi yi-US namanye amabutho ezempi.
