'Chinese Navy ship seen carrying railgun'

Click For Summary

Discussion Overview

The discussion centers on the development and implications of electromagnetic railguns, particularly in the context of the Chinese Navy's advancements and the status of similar programs in the United States. Participants explore technical challenges, power requirements, and the viability of railguns as naval weaponry.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • Some participants note that the Chinese Navy claims to be leading in railgun technology, emphasizing that their designs are based on independent intellectual property.
  • Others argue that the primary challenge for railguns is their power requirements, suggesting that only nuclear-powered ships could effectively support them.
  • Concerns are raised regarding the U.S. Navy's firing rate limitations, with some participants citing a discrepancy between current rates and desired performance levels, potentially linked to insufficient electrical power.
  • Discussion includes skepticism about the wear and tear on railgun barrels, questioning whether advancements have been made to address this issue.
  • Some participants mention that the U.S. railgun program appears to be canceled, indicating a shift in feasibility assessments despite solid physics and engineering foundations.

Areas of Agreement / Disagreement

Participants express a range of views on the feasibility and future of railgun technology, with no consensus reached on the viability of current developments or the implications for naval warfare.

Contextual Notes

Participants highlight limitations related to power supply, firing rates, and material durability, which remain unresolved in the discussion.

China says its navy is taking the lead in game-changing electromagnetic railguns
Headline said:
China’s landing of a rover on the far side of the moon grabbed headlines around the world this week. Less noticed, the country’s state media reported on progress in another arena: game-changing naval weaponry.

The state-run Global Times said on Thursday (Jan. 3) that Chinese warships will soon be equipped with electromagnetic railguns that fire projectiles with “incredibly destructive velocity,” and that the underlying technology was based on ”fully independent intellectual property,” rather than designs copied from other nations. It cited a report that appeared Wednesday on China’s CCTV.
Rest of the article is on the site. The news is available on multiple news outlets, including pictures on Twitter.

I recall the US Navy was developing a railgun a few years ago, while Russia was still in the R&D phase a year ago...

I thought the issue with rail guns was not that they are difficult to build but that the power requirements mean that only a nuclear powered ship was capable of housing one. The navy seems to believe they are the future - longer range, more on-ship ammo storage and no risk from storing explosive material

Google tells me the USA is having an issue with firing rate (4.8 rounds per minute vs a required 10), which may be a result of not enough electrical power available. It does seem like a pretty fundamental problem.

Clearly they just need to add a few more batteries. :rolleyes:

But seriously, I thought the major hurdle was wear and tear on the barrel. Has sufficient progress been made on that end to turn rail guns into viable weapons (minus the power problems)?

Looks like the US 'railgun' program is history.

https://www.thedrive.com/the-war-zo...y-railguns-and-deck-guns-killed-off-in-budget
Earlier this week, The War Zone was first to report the U.S. Navy's program to develop an electromagnetic railgun appeared to be all but formally canceled in its proposed budget for the 2022 Fiscal Year. Now, it has also emerged from that service's budget request that it plans to stop working on the specialized, high-speed, multi-purpose projectiles for that weapon, versions of which were also being developed for use in other more conventional guns, at least for the time being.



Looks like the physics and engineering were pretty solid. Possible, Yes. Feasible, No.
