Rade na defanzivnom laseru za obaranje raketa koji bi se kao kontejner mogao nositi i na postojecim F-22 i F-35.
USAF considers defensive lasers for future fighters
Citat:The dawn of the combat laser era might begin in 2021 when the US air force hopes to begin demonstrations of a podded electric laser system for fifth and sixth-generation fighter jets that can destroy incoming missiles, not just steer them off course.
Today, the air force research laboratory started gathering market information under an advanced technology demonstration programme known as SHiELD, or self-protect high-energy laser demonstrator.
According to the request for information notice, the project seeks to integrate a “moderate power” electric laser into a protective pod for supersonic combat jets, including fifth-generation jets like the Lockheed Martin F-35 and F-22 as well as future fighters and bombers.
“SHiELD seeks to expand moderate power (tens of kilowatts) laser weapon operation into the supersonic regime by demonstrating system performance under transonic flight, and acquiring aero-effects data under a supersonic environment relevant to current and future tactical aircraft,” the notice states.
“Advanced laser options under investigation are those with size and weight appropriate for integration as part of a complete laser weapon system into an aerodynamic integrated pod-like structure carried by a tactical aircraft.”
The laser pod would be significantly more powerful than current-generation self-protection capabilities like Northrop Grumman’s directional infrared countermeasure (DIRCM) system. It’s added power could burn or otherwise disable infrared and radar-guided missiles at high speeds.
Military scientists hope to validate the laser pod in a laboratory environment (technology readiness level four) by 2017 and be ready for prototype demonstration by 2021, the notice says.
The air force has long sought to introduce airborne laser weapons, but the technology remains elusive. Lockheed Martin has explored laser weapon options for the F-35, and US special operations forces want to install a laser gun on the new AC-130J Ghostrider gunship by 2020.
Instead of chemical lasers that were favoured for the defunct Boeing YAL-1A airborne laser testbed, air force and industry officials now see electric-powered lasers as the best way forward.

posto su ameri i ovako odmakli sa ovim generacijama (najblizi konkurenti imaju tek prototipove 5 gen, ostali ni to), zar ne bi bilo jeftinije ponovo pokrenuti liniju za f22, i nabudziti ga najnovijim tehnologijama?
ustedeli bi gomile para sto bi dali u razvoj. ovako bi vec imali osnovu, i samo bi trebalo da dograde.
imali bi recimo avionce generacije 5++
+ ne bi cekali 20 god na razvoj nego bi za 2-4 god imali novu igracku

Ne znam kako si dosao do toga ali ne moze to tako. Ovo sto sam ja postavio u poslednjih par strana je sve u labartorijskoj fazi razvoja. A sve ovo sto northrop prica o toploti i laserima zahteva novu platformu gde ce to sve da smeste. Nista posebno nebi dobio sa totalnim redizajnom dizajna starog 20 godina. Cak naprotiv.
Ovi dizajni leteceg krila ce omoguciti mnogo veci dolet/vreme ostajanja u vazduhu bez tankanja sto je jedan od zahteva. Veci nivo stelta, novi materijali, novi motori sa promenljivim ciklusom rada... Nekakav novi radar jos ni ne spominju...

Da ne postoji od lasera vrlo jeftina odbrana tj premazi ko odbijaju zrake?

Toni ::Ma kakav crni premaz, nisu to zastitne naocare, ovde se govori o laserima koji mogu da progore raketu ili zmaj letelice. Vec su pokazali kako se przi BPL http://www.mycity-military.com/PVO-i-sistemi-VOJ/Laseri-kao-PVO.html
Sve je to lepo ali
Prema zahtjevima Ministarstva gospodarstva i trgovine RF (Minpromtorga) polietilenska oklopna zaštita treba izdržati udar bojevog lasera, pogodak pancirnog metka 12.7 mm s udaljenosti 300 m i eksploziju 8 kg trinitrotoluena, djelovanje „plamena snage 10 W/cm² tijekom 15 s, svjetlosnog impulsa snage 42 J/cm² u trajanju od 1 s; lasera SO2 snage 42 W/cm² tijekom 25 s”.

Citao sam da postoje odavno premazi kojima su jos Sovjeti,a sada Rusi premazivali svoje balisticke rakete kako bi ih zastitele od lasera... Tako da laseri nemaju neki potencijal toliko veliki da od njih pravimo neko nebesko ili van zemaljsko oruzje.

Posto su napisali odbrambeni verovatno misle na odbranu od raketa sumljam da misle na laser koji moze da obori avion.

Znao sam da imas neki ruski link koji si ti razumeo kako samo ti umes...
Materijal za oklop http://izvestia.ru/news/555976 a ne premaz kako ti pricas. I ovde ti je tt zahtev da izdrzi koliko tu pise wata ? A ovi prze bpl sa 10 kw a rade laser od 100 kw koji ce biti gotov 2018. A kako ce izgledati ovo sto northrop radi za buduci lovac uopste ni nemamo predstavu.

Naravno odbrambeni.

Inace laser ima dosta logike pogotovo u eri steltova. IRST sistemi su sve bitniji zbog slabih mogucnosti radara protiv stelt letelica i laser bi bio dobra opcija da se osteti IRST na protivnickom lovcu, nesto slicno ofanzivnom laseru koji Kinezi ugradjuju na Type-99 tenk.
