Military / Modern Chinese destroyer breaks down in the Indian Ocean
« Last post by VH on Yesterday at 04:17:44 pm »
A PLAN destroyer, 173 Changsha , of Type 052D , broke down in the Indian Ocean on the way to the Sino-Russian naval exercise "Joint Sea 2017". She is one of China's latest destroyers

Another destroyer, the 174 Hefei, of the same class has replaced it.

Destroyer 173 Changsha , frigate 571  Yuncheng of Type 054A and tanker-tanker 964  Luomahu of Type 903A  constituted the Chinese fleet which left the port of Sanya on Sunday June 18th . However the 173 Changsha "disappeared" from official communications and her sistership 174 Hefei replaced it to lead the other two ships to the joint exercise in St. Petersburg and Kaliningrad.

RG 342
Entry P-26
Sarah Clark Central Decimal Correspondence
Box 3684
NND 917647



Wright-Patterson AFB
Dayton, Ohio

14 October 1948


SERIAL NO:           TI 2116

SUBJECT:               Development of Strategic Reconnaissance Aircraft XR-16

TO:                          Directorate, Research & Development

1. Problem Presented:

a. To develop an aircraft that will meet the requirements outlined in the "Military Characteristics for Strategic Reconnaissance Aircraft" dated 3 August 1948.

2. Factual Data:

a. It is desired that the military characteristics for this type aircraft be loosely construed in order to enable industry to more fully utilize its design research and initiative in developing USAF aircraft.

b. In accordance with the Aircraft Weapons Board decision of January, 1948, the development of this Strategic Reconnaissance airplane has a priority lower than the XB-52 and higher than the XB-55. It is urgent that aggressive effort be applied to this development so that production quantities may be obtained at the earliest possible date.

3. Authority:

a, C/S USAF by 2nd Indorsement, dated August 17, 1948 to basic letter dated 5 May 1948 subj: "Strategic Reconnaissance Aircraft Characteristics."

4. Action Desired:

a. Directorate, Research & Development will accomplish that which is required under "Problem Presented."

b. A priority of 1-B is assigned to this project.

I can hear structural engineers all across the country laughing their a$$es off when they see that design. "Hmmm, what if we made it as structurally inefficient as possible to make it much heavier than it needs to be?"

David K Brown was probably the closest thing we will ever get to a British Norman Friedman; unfortunately he's been gone for some time.

You might try Friedman's "The Postwar Naval Revolution", which concentrates extensively on British ships - planned and built - and the weapon systems they hoped to carry, "British Cruisers: Two World Wars and After", and also Brown's "Rebuilding the Royal Navy".

Electromagnetic railgun will demo 10 rounds per minute

By the end of 2018, the Navy will test an electromagnetic railgun that can shoot 10 rounds per minute, according to a service official.

Within the year, Thomas Beutner, Naval Air Warfare and Weapons department head at the Office of Naval Research, told reporters July 20, a 32 megajoules electromagnetic railgun will be demonstrated at Naval Surface Warfare Center Dalhgren, VA, using a new composite launcher firing at 10 rounds per minute.

The service will also conduct the first-ever hypervelocity projectile flight demonstration in 2019, Beutner said.

In fiscal year 2019, the Navy will test the electromagnetic railgun with a series of different barrels to determine the best one for the fleet, Thomas Boucher, Naval Air Warfare and Weapons department program officer, said during the same presentation.

ONR will conclude its electromagnetic railgun program at the end of FY-19. Naval Sea Systems Command's program executive office for integrated weapons systems has a directed-energy program office that will then take the reins and determine the path ahead for the system.

A shame they cancelled the only class of ships that could realistically support such a weapon.

The Global Combat Ship for Australia

Published on Jun 22, 2017

A next-generation capability to secure Australian jobs for generations.

For the SEA5000 program BAE Systems will offer the Commonwealth the export version of the Type 26 - our Global Combat Ship (GCS). The GCS is the newest, most advanced and most capable Anti-Submarine Warfare (ASW) platform in the world. Purpose designed for ASW, the GCS combines superior acoustic stealth with peerless general purpose capabilities, exemplified by the multi-mission bay, which provides unparalleled mission flexibility.

"BAE Systems is offering the Royal Navyís Type 26 Global Combat Ship (GCS) design for the Canadian Surface Combatant (CSC) program"


We believe Type 26 GCS could be the right solution for CSC.  The ship meets Canada's high-level requirements - already released - and will be capable of deployment worldwide for extended periods, undertaking a wide range of roles from high intensity conflict to humanitarian assistance, including anti-submarine warfare and air defence.  It is flexible, versatile and is highly survivable with an extremely low acoustic signature. The Type 26 design is tailored to be inherently flexible to accommodate the different ways that international customers build their ships, minimising cost and risk.
Modular design
The keys to the vesselís ability to meet the Canadian requirement and to accommodate Canada-specific sub-systems are its modular design and open systems architecture. The same features will also minimise cost of ownership and facilitate Canadian industry playing a leading role in through-life support and upgrade; delivering long term economic benefit to Canada.
150 years' heritage
At BAE Systems we have more than 150 years' heritage in warship design, and over the last 50 years have designed and built some of the quietest ships and submarines ever deployed.  These low acoustic signatures are crucial for ships to evade detection from submarines, which ultimately translates into the safety and survivability of the crew, and the ability of the ship to successfully complete its mission.

Marauder, you seem to ignore that the proposal limits the qty of warheads available for offensive, disarming action.
