INS Arihant left crippled after ‘accident’ 10 months ago

Nuclear submarine was damaged after water entered its propulsion chamber

Indigenous nuclear submarine INS Arihant has suffered major damage due to ''human error'' and has not sailed now for more than 10 months, say sources in the Navy.

Arihant is the most important platform within India’s nuclear triad covering land-air-sea modes.

Arihant’s propulsion compartment was damaged after water entered it, according to details available with The Hindu. A naval source said water rushed in as a hatch on the rear side was left open by mistake while it was at harbour.

The Ministry of Defence did not respond to questions from The Hindu.

-the USN has no immediate plans on a LRLAP replacement

-Captain Kirk’s comments could be interpreted as the USN waiting for 155mm HVP rounds

-the Zumwalts are being repurposed for surface combat instead of supporting amphibious assaults

FGS Baden-Württemberg has reportedly been returned to Blohm+Voss after failing trials

 

Quote

Defects cited in the news report include software and hardware issues, likely the same ones which caused her to miss her commissioning deadline this summer. As Naval Today reported earlier, there are problems with the frigate’s operations room from where the highly-automated ship will be controlled.

 

This is a complex system as the 7000-tonne frigate (close to the displacement range of a destroyer) will require only half the crew necessary to operate the predecessor Bremen-class frigates.

 

FGS Baden-Württemberg has been experiencing problems ever since it was delivered to the navy for trials. In addition to hardware and software integration, the frigates have a listing problem. They list 1.3 degrees to starboard and are overweight, an issue that could possibly complicate future upgrade options.

How many ships that listed while fresh out of the shipyards were accepted for service?

I can see some logic to it. You're essentially making a silo launched missile (might be cheaper than SSBN, on station most of the time unlike SSBN) that can't be seen by satellite.

 

In other news, a big grey british floaty thing has floated out of harbour for initial aircraft trials:

Helicopters join HMS Queen Elizabeth as she sails on first aircraft trials

02/02/2018

Chinook helicopters have landed on board HMS Queen Elizabeth for the first time as the Royal Navy's new aircraft carrier heads to sea on her next round of trials.

The UK's future flagship sailed from Portsmouth today for the first time since being officially commissioned into the Royal Navy in December. She will be launching her first helicopter trials at sea.

 

Two Chinooks from the Aircraft Test and Evaluation facility at MOD Boscombe Down arrived on board this morning as the carrier prepared to sail. The ship will be joined later by two Merlin Mk2 aircraft, with all four aircraft carrying specialist testing equipment...

 

...HMS Queen Elizabeth's 700-strong crew will be further bolstered during the trials by more than 70 people from the ship's permanently assigned Naval Air Squadron, 820 NAS from RNAS Culdrose, with two further operational Merlin helicopters providing force protection.

 

Of note is that there is two operational merlins on board for "force protection", so this is iIOC! Initial initial operating capability!

Most likely your image is made of this.

Which was taken from here - http://militaryrussia.ru/forum/viewtopic.php?p=99954. The photo was uploaded in April 2016, but it is claimed that it was made back in 2009. In the forum that I gave, discussed skiff and kanyon. Therefore, it is not a fact that it is kanyon. It is more likely to be skiff.(http://sdelano-u-nas.diary.ru/p188489617.htm This is about skiff) But, it's also not a fact that it's a skiff. I would wait a while before uploading this photo, until nothing is explained about it. (Before writing my comment, I did not read the link, which led LoooSeR,)

If the google or bing translate fucks it up to much, tell me and I will try to translate the technical terminology gibberish for you.
