Railguns auf Schiffen

[fusil]

Grundsätzlich schon, nur brauchst du eben eine Isolierung welche ebenfalls magnetisch ist oder sich zur Verwendung mit einem Treibkäfig eignet, weiters muss sie der auftretenden Luftreibung gut widerstehen können!

Ich habe kein passendes Thema gefunden. Es gibt zwar ein altes über Railgun-Munition unter Landgestützte Systeme, aber das ist sehr eng gefasst.

160 Kilometer Reichweite
US-Marine testet neue Superkanone für Schiffe

Ich frag mich ob das mit 160km ernst gemeint ist.
Die Reichweite fast zu verzehnfachen wäre schließlich kein Pappenstiel.

Und aus dem anderen Thread würde ich mal nochmal die Frage aufwerfen, ob es vom Aufwand her sinnvoll möglich ist, andere außer Wuchtgeschosse zu verschießen. Ich hab keine Ahnung, wie sich die starken Magnetfelder auf Zünder, Sensorik und Sprengstoff auswirken.

[Nahkampfhase]

Ernst gemeint ist es ganz sicher! Hab schon ähnliche gelesen.

Ein Explosivgeschoss, was von einer Rail Gun abgefeuert würde, wäre siche rlangsamer als ein Wuchtgeschoss gleichen Kalibers aber hätte schon noch eine passable Geschwindigkeit. Ausserdem würden auch da kein Rückstoss und kein Mündungsfeuer auftreten. Dass Geschoss wäre dann wohl so aufgebaut, dass aussen eine Hülle aus magnetischem metall ist, dann eine Isolierungsschicht und innen der Spengstoff. Wenn man einen primitiven chemischen Aufschlagzünder benutzt, müsste es eigentlich gehn.

Eigentlich reicht bei einer Railguns sogar zwei "Schienen" am Geschoss, die bescheunligt werden.

Die hohe Reichweite ergibt sich aus der sehr hohen V0 des Geschütztes. das in der Atmosphäre nur durch den Luftwiderstand begrenzt wird, theoretisch.

Zufällig gefunden (Meldung von Juli d. J.) und alten Strang "ausgegraben": Die Thematik Railgun bzw. Gauss-Geschütze scheint sich wohl erledigt zu haben...

US Navy ditches futuristic railgun, eyes hypersonic missiles

BATH, Maine — The U.S. Navy has pulled the plug, for now, on a futuristic weapon that fires projectiles at up to seven times the speed of sound using electricity.

The Navy spent more than a decade developing the electromagnetic railgun and once considered putting them on the new, stealthy Zumwalt-class destroyers built at Maine’s Bath Iron Works. But the Defense Department is turning its attention to hypersonic missiles to keep up with China and Russia, and the Navy cut funding for railgun research from its latest budget proposal. “The railgun is, for the moment, dead,” said Matthew Caris, a defense analyst at consultancy Avascent Group. [...]

All told, the Navy spent about $500 million on research and development, according to Bryan Clark, an analyst at the Hudson Institute. The technology was close to making the leap from science fiction to reality in the 21st century with the testing of prototypes. [...] But there were a number of problems. Those included the range of about 110 miles in testing. A Navy vessel could not employ the gun without putting itself within range of a barrage of enemy missiles.

Report on Navy Laser, Railgun and Gun-Launched Guided Projectiles

This report provides background information and issues for Congress on three potential new ship-based self-defense weapons for the Navy—solid-state lasers (SSLs), the electromagnetic railgun (EMRG), and the gun-launched guided projectile (GLGP), also known as the hypervelocity projectile (HVP). The Navy’s proposed FY2022 budget requests research and development funding for continued work on SSLs, but proposes suspending further work on the EMRG and GLGP programs and requests no research and development funding for them.

The Navy installed its first prototype SSL capable of countering surface craft and unmanned aerial vehicles (UAVs) on a Navy ship in 2014. The Navy since then has been [...] installing additional SSL prototypes with improved capability for countering surface craft and UAVs. Higher-power SSLs being developed by the Navy are to have a capability for countering anti-ship cruise missiles (ASCMs). Current Navy efforts to develop SSLs include:

- the Solid State Laser Technology Maturation (SSL-TM) effort;
- the Optical Dazzling Interdictor, Navy (ODIN);
- the Surface Navy Laser Weapon System (SNLWS) Increment 1, also known as the high-energy laser with integrated optical dazzler and surveillance (HELIOS); and
- the High Energy Laser Counter-ASCM Program (HELCAP).

The first three SSL efforts listed above are included in what the Navy calls the Navy Laser Family of Systems (NFLoS). [...] It was originally conceived as a naval surface fire support (NSFS) weapon for supporting Marines and other friendly forces ashore. Subsequently, it was determined that EMRG could also be used for air and missile defense, which for a time strengthened Navy interest in EMRG development. As the Navy was developing EMRG, it realized that the guided projectile being developed for EMRG could also be fired from powder guns, including 5-inch guns on Navy cruisers and destroyers and 155 mm artillery guns operated by the Army and Marine Corps. The concept of firing the projectile from powder guns is referred to as GLGP and HVP.

Nun denn, also auf den ersten Moment nun doch wieder keine Railguns...theoretisch...
