Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source. Clickbait titles may be removed.

Clickbait titles use hyperbolic language and do not accurately describe the article content. When necessary, post titles may be edited, clearly marked with [brackets], but may never be used to editorialize or comment on the content.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials, videos, press releases, or celebrity gossip will be allowed. All posts will be judged on a case-by-case basis. Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.
7. No duplicate posts.
If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners or news aggregators.
All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link. Newswire services such as AP, Reuters, or AFP, are frequently republished and may be shared from other credible sources.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

The issue between the two systems is isolation. In the old C-13 series if one track needed repair, you have to shut steam off to that track. The rest can keep going. In the EMALS there's just the one centralize power architecture, so if a track has to go down, it takes the whole thing down with it.
Few really want to return to steam. It requires a lot of the ship to house special high pressure equipment and requires more maintenance overall to keep it running. Additionally, a lot of the drones designed need the precise control that the EMALS provides to not break apart. But it's hard to point out all the various tooling that has to go on behind the scenes when one track goes down with steam, when the whole effing thing with EMALS has to go down and no launching happens for hours.
And that's ultimately what happens, the metrics that are being used are getting aircraft into the air, not overall downtime or cost to operate. And EMALS is still struggling to hit the numbers it has to hit and likely won't hit them till around 2030. Every time it goes down, every zero aircrafts it gets pulls that metric down hard.
You'd think that an electric system should allow for relatively easy isolation – isolating electric circuits from each other with breakers is hardly new technology. Is this lack of isolation a design flaw of EMALS or is there an actual physical reason why it couldn't be designed with independently powerable tracks?
Looks like they've already issued a contract to fix it so it would appear it's entirely possible and someone just fucked up the requirements/design first time around.
Absolutely wild that this wasn't part of the original design. I can turn off power to my stove without shutting down my whole house, but the US Navy can't independently power launch systems.
You'd think the United States would take great care when designing their main tools for global power projection. And you'd probably be right; I can imagine that countless hours were invested into determining where the parts get built and which senators get to politically benefit from that. Technological details don't really matter; at worst you can just turn flaws into lucrative followup contracts for companies in the stock portfolios of top politicians.
I’m wondering if they mean that the points of failure are overall harder to isolate? Like, I don’t know… can the steam system work if the ship looses power? That would be a level of isolation that I imagine EMALS can’t do. But then I’d wonder, what if each track had its own generator? Oh… hey, just use steam generators. Problem solved, Trump won’t tell the difference,
But her EMALS
(sorry, I actually enjoyed your contribution though)
5 stars, that was a good one!
5 stars is truly top-tier, in general
*coughs* Ok, I'm leaving
US military too dumb to isolate a track electrically, checks out
