ဘီ-၂ ကိုယ်ပျောက်ဗုံးကြဲလေယာဉ် In contrast to the flat surfaces of the earlier F-117 Nighthawk, the B-2 is composed of many curved and rounded surfaces across its exposed airframe to deflect radar beams, additional reduction in its radar signature was achieved by the use of various radar-absorbent materials (RAM) to absorb and neutralise radar beams. The B-2's clean, low-drag flying wing configuration not only gave it exceptional range, but was also beneficial to reducing its radar profile as well.
ဘီ-၂ ကိုယ်ပျောက်ဗုံးကြဲလေယာဉ် In addition to periodic software upgrades and the introduction of new radar-absorbent materials across the fleet, the B-2 has had several major upgrades to its avionics and combat systems. For battlefield communications, both Link-16 and a high frequency satellite link have been installed, compatibility with various new munitions has been undertaken, and the AN/APQ-181 radar's operational frequency was shifted in order to avoid interference with other operator's equipment. The upgraded radar features entirely replaced arrays by those of a newer design, the AN/APQ-181 is now an Active Electronically Scanned Array (AESA) radar.
ဘီ-၂ ကိုယ်ပျောက်ဗုံးကြဲလေယာဉ် By the mid-1970s, it was becoming clear that there was a different way to avoid missiles "and" intercepts; known today as "stealth"; the concept was to build an aircraft with an airframe that deflected or absorbed radar signals so that little was reflected back to the radar unit. An aircraft having stealth characteristics would be able to fly nearly undetected and could be attacked only by weapons and systems not relying on radar. Although such possibilities existed such as human observation, their relatively short detection range allowed most aircraft to fly undetected by defenses, especially at night.
ဘီ-၂ ကိုယ်ပျောက်ဗုံးကြဲလေယာဉ် The B-2's low-observable, or "stealth", characteristics enable the safe penetration of sophisticated anti-aircraft defenses and to attack even heavily defended targets. This stealth comes from a combination of reduced acoustic, infrared, visual and radar signatures to evade the various detection systems that could be used to detect and be used to direct attacks against an aircraft. The majority of the B-2 is made out of a carbon-graphite composite material that is stronger than steel and lighter than aluminium, perhaps most crucially it also absorbs a significant amount of radar energy. Reportedly, the B-2 Spirit has a radar signature of about 0.1 m.
ဘီ-၂ ကိုယ်ပျောက်ဗုံးကြဲလေယာဉ် Innovations such as alternate high-frequency material (AHFM) and automated material application methods were also incorporated into the aircraft to enhance its radar-absorbent properties and lower maintenance requirements. In early 2004, Northrop Grumman began applying a newly-developed AHFM to operational B-2s. In order to protect the operational integrity of its sophisticated radar absorbent material and coatings, each B-2 is kept inside a climate-controlled hangar large enough to accommodate its wingspan.
ဟော်တင်ဟို ၂၂၉ လေယာဉ် Since the appearance of the B-2 Spirit flying wing stealth bomber in the 1990s, its similarities in role and shape to the Ho 229 has led many to retroactively describe the Ho 229 as "the first stealth bomber". A captured Ho 229 was later tested by the US military who found the basic shape and paint composition provided limited protection against the crude Chain Home radar of the 1940s, but no stealth benefit against modern radar.

ဆလီနီအာကာသယာဉ် On October 31, 2007, Kaguya deployed its Lunar Magnetometer, Lunar Radar Sounder, Earth-looking Upper Atmosphere and Plasma Imager. On December 21, 2007, Kaguya began regular operations after all fifteen observation experiments had been satisfactorily verified.
ဘီ-၂ ကိုယ်ပျောက်ဗုံးကြဲလေယာဉ် In 1974, DARPA requested information from U.S. aviation firms about the largest radar cross-section of an aircraft that would remain effectively invisible to radars. Initially, Northrop and McDonnell Douglas were selected for further development. Lockheed had experience in this field due to developing the Lockheed A-12 and SR-71, which included a number of stealthy features, notably its canted vertical stabilizers, the use of composite materials in key locations, and the overall surface finish in radar-absorbing paint. A key improvement was the introduction of computer models used to predict the radar reflections from flat surfaces where collected data drove the design of a "faceted" aircraft. Development of the first such designs started in 1975 with "the hopeless diamond", a model Lockheed built to test the concept.
ဘီ-၂ ကိုယ်ပျောက်ဗုံးကြဲလေယာဉ် ဘီ-၂ အား ယခင်ဗုံးကြဲလေယာဉ်များထက်ပိုမိုထိရောက်စေရန်အတွက် ယင်းဒီဇိုင်းတွင် ခေတ်ပါ်ပျံသန်းခြင်းနည်းစနစ်များကို ပေါင်းစပ်ထားသည်။, these have been modified and improved in light of the switch to conventional warfare missions. The B-2 features the low probability of intercept AN/APQ-181 multi-mode radar, a fully digital navigation system that is integrated with terrain-following radar and Global Positioning System (GPS) guidance, and a Defensive Management System (DMS) to inform the flight crew against possible threats. The onboard DMS is capable of automatically assessing the detection capabilities of identified threats and indicated targets.
