This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 35.175.0.0/16 has been blocked (disabled) by ‪JJMC89‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 05:20, 2 March 2025.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

'''HMS ''Diadem''''' was a ((sclass|Dido|cruiser|0)) [[light cruiser]] of the ''Bellona'' subgroup of the [[Royal Navy]]. She was a modified ''Dido'' design with only four [[gun turret|turret]]s but improved anti-aircraft armament – also known as ''Dido'' Group 2. She was built by [[Hawthorn Leslie and Company]] at [[Hebburn|Hebburn-on-Tyne]], [[United Kingdom|UK]], with the keel being laid down on 15 December 1939.<ref name="Conways">Campbell, p. 35</ref><ref name="Lenton">Lenton, p. 67</ref> She was launched on 26 August 1942,<ref name="Conways" /><ref name="Lenton"/> and completed on 6 January 1944.<ref name="Conways" /><ref name="Lenton"/>

==Service history==

===Royal Navy service===
''Diadem'' served on the [[Arctic convoys]] and covered carrier raids against the ((ship|German battleship|Tirpitz)) in the early months of 1944, then became part of Force G off [[Juno Beach]] during the [[invasion of Normandy]] in June. After the landings she carried out offensive patrols against German shipping around the [[Brittany]] coast, sinking, with destroyers, ''[[Sperrbrecher]] 7'' off [[La Rochelle]] on 12 August. She returned to northern waters in September, where she covered Russian convoys and carrier raids against German shipping routes along the Norwegian coast, as well as making offensive sweeps herself. In the course of one such sweep, accompanied by ((HMS|Mauritius|80|6)) on 28 January 1945, the cruiser [[Action of 28 January 1945|engaged three German destroyers]], damaging ((ship|German destroyer|Z31||2)). ''Diadem'' remained with the 10th Cruiser Squadron until after the war, and served in the [[Home Fleet]] until 1950. She was placed in reserve between 1950 and 1956.((citation needed|date=July 2016)) A more extensive modernisation than [[HMS Royalist (89)|HMS ''Royalist'']]''<nowiki/>'s'' 1953-6 refit with new boilers and anti-nuclear washdown for Diadem as [[NATO]] flagship and AA/AD escort was canceled in 1954 on grounds of cost, the manual hand loaded armament requiring lifting 82lb shells, lack of space for crew and the non military functions of a cruiser, entertaing potential friends of Britain and carrying disaster relief resources. The transfer of ''Diadem''to Pakistan was on the pretext the ship would serve as a training ship, but in fact was a RN move, to balance the INS purchase of [[HMS Nigeria (60)|HMS ''Nigeria'']] as arranged by First Lord Mountbatten in 1955 <ref>First Sea Lord Minute of 7 Oct 1955 in Mountbatten Papers in  J. Goldrick. Imprial Jetsma or National Interest. The Navies of the Indian Subcontinent in N. Roger. Naval Power in the 20C. MacMillan  91978) p 204 & 212, nb 15</ref>

She was sold to the Pakistan Navy (announced) 29 February 1956 and refitted at Portsmouth Dockyard before being handed over to the Pakistan Navy as Babur on 5 July 1957.<ref>Blackman, Raymond V B, Jane's Fighting Ships 1967–68, Sampson Low, Marston & Co. Ltd, London, p210</ref>

=== Pakistan service ===

((other ships|PNS Babur))

The refit was substantial, the light armament was standardised, fourteen new L60 40mm guns in three twin  Mk 5 mounts and eight single  Mk 7 mounts  as on INS ''Mysore'' (ex-HMS ''Nigeria''). Radar was substantially updated to Type 974 navigation, Type 293 target indicator and air warning 281B at near 960 capability and ADR similar to HMS ''Euralyus'' the last operational RN Dido 11/1954.  A new bridge was fitted and the ship tropicalised. Surface and long range AA for the 5.25 turrets remained (2)WW2 standard 984/985 as on ''INS Delhi''. She was renamed ''Babur'', after the [[Babur|founder of the Mogul empire]]. The cost of the refit far exceeded the £400,000 allocated by the Pakistan Government <ref>J. Goldrick RAN.ret. No Easy answer. The development of the Navies of India, Pakistan, Bangladesh & Sri Lanka 1945–1996. Lancer.(1997) Delhi, p62</ref> even supplemented with a 0.25 million dollar, US MDAP aid grant, and the refit by the Royal Navy dockyard, charged below cost. Pakistan still had to meet a huge shortfall in the bill. It had been known from the start of 1956 that the refit cost would exceed Pakistan's budget, but the new First Sea Lord, Mountbatten, the last Viceroy of India, was determined Pakistan would have a cruiser, as was head of Pakistan's navy Choudri. Despite his government's attempt to first cancel the deal in mid-1957, then demand the cruiser be decommissioned as an extravagance when it arrived in 1958, the British Government demanded a payment, which even the British [[British Far East Command|Far East Command]] considered outrageous and likely to promote a political crisis.<ref>J Goldrick.

Light 37mm AA and 40/60 Bofors at Karachi and other ports discouraged low level Indian Air Force bombing, below 2 miles high in IAF Canberra raids that occurred on Karachi. This led India to develop a plan to use its Styx-equipped [[Osa missile boat]]s squadron with only Russian spoken in the Osa boats operation rooms for security, deception and commonality with the Indian officers trained in Russia for its major strike against the Pakistan Navy and the Karachi port installations and oil refineries. As the Osa missile boat squadron one Pakistan  Battle class  destroyers was sunk by 2 Styx missiles and another second hand Pakistan destroyer of the RN C class was massively damaged by another Styx (both the Battle and C class Destroyers were still in RN service itself at the time in 1971).  The 27 year old cruiser ''Babur'' somehow being missed, possibly due to its fitting with standard USN ESM/ECM similar to HMAS ''Yarram'' enabling the  ''Babur'' to electronically black itself out in time. Later during the night, after the failure of repeated Indian air force air strikes the Karachi tank farm of  oil storage facilities, were hit by Styx missiles from Osa missile boats causing a firestorm. ''Babur'' lacking anti-missile protection and ability to identify air and surface unit attacks was recalled to the naval base as a static flag ship. In 1982 it was renamed ''Jahangir'' as it was replaced by the newly purchased [[County-class destroyer]] [[HMS London (D16)|HMS London]], which itself was renamed ''Babur''. ''Jahanqir'' was broken up in 1985.<ref name="Conways2">((cite book |editor1-last=Gardiner |editor1-first=Robert |editor2-last=Chumbley |editor2-first=Stephen |editor3-last=Budzbon |editor3-first=Przemysław |title=Conway's All the World's Fighting Ships 1947-1995 |date=1995 |publisher=Naval Institute Press |isbn=1-55750-132-7 |page=299 |edition=illustrated, revised |chapter=Pakistan))</ref>
