The SPR-2 "Rtut-B" (1L29) is a Soviet jamming station designed for artillery munitions radio detonators, developed on a BTR-70 armored personnel carrier at the "Gradient" institute. During development, it was transitioned to the BTR-80.

The Northrop B-2 Spirit, also known as the Stealth Bomber, [3] is an American heavy strategic bomber, featuring low-observable stealth technology designed to penetrate dense anti-aircraft defenses.

The U.S. Air Force's B-2 stealth bomber is a key component of the nation's long-range strike arsenal, and one of the most survivable aircraft in the world. Its unique stealth characteristics allow it to penetrate the most sophisticated enemy defenses.

spr-2電子戰系統（俄語： СПР-2 ）是蘇聯開發的一種干擾彈藥無線電引信的電子戰系統，grau代碼為1Л29，也稱為水星-b，或者水銀-b。 最初以 BTR-70 裝甲車為底盤開發，後來又改進為 BTR-80 。

表面等离子体共振（Surface Plasmon Resonance, SPR）是一种高灵敏度的生物传感技术，通过监测生物分子在金属薄膜表面的相互作用，实时、无标记地提供结合动力学和亲和力数据，广泛应用于分子互作检测。 SPR 技术的核心是利用光在不同介质中产生消逝波后与金属表面的等离子波产生共振，当固定在芯片上的配体和流经芯片的分析物发生结合和解离时，芯片表面质量变化造成共振角发生变化，传感图会实时记录相互作用下的信号值，根据此变化曲线从而得出分子间相 …

2016年8月25日 · SPR-2 is able to cause premature explosion at a safe height or switch the fuse into contact mode. The main areas of use are the first echelon troops, command posts, concentrations of troops and missile launchers. Also, the Rtut-BM can be used to protect the moving objects at pontoon bridge crossings.

The B-2 Spirit is a multi-role bomber capable of delivering both conventional and nuclear munitions; bringing massive firepower to bear, in a short time, anywhere on the globe through previously impenetrable defenses.,

The B-2 Spirit is a multi-role bomber capable of delivering both conventional and nuclear munitions. A dramatic leap forward in technology, the B-2 brings massive firepower to bear, in a short time, anywhere on the globe through previously impenetrable,

The prototype B-2 stealth bomber emerged in 1988 after a decade of top secret research by the US Air Force. The B-2 design made great strides over previous attempts at stealth aircraft, such as the B-1B and F-117, thanks to a more refined understanding of radar wave reflection and its aerodynamic flying wing shape.
