You do not have permission to edit this page, for the following reasons:

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 34.200.0.0/16 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 05:16, 2 September 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.

((cleanup|reason=information should be included in the "short summary" section of the table describing their overall history.|date=January 2022))
A '''Landing Ship Medium''' (LSM) was an [[amphibious assault ship]] of the [[United States Navy]] in [[World War II]].  Of a size between that of [[Landing Ship, Tank|Landing Ships Tank]] <!-- (LST) --> and [[Landing Craft Infantry]]<!-- (LCI) -->, 558 LSMs were built for the USN between 1944 and 1945. Most of vessels built on this frame were regular transports, while several dozen were converted during construction to specialized roles. Most LSMs were scrapped during the [[Cold War]], but several were sold by the [[United States Department of Defense]] to foreign nations or private shipping companies.

OPNAV N95 established a new LSM program in 2020. The new LSM will be 350 to 400 ft long, able to operate at 22 knots and have a range of 6500 miles. The cost will be much lower than traditional amphibious shipping, according to a story in the March 2023 Marine Corps Gazette.  The piece suggests that a MLR (Marine Littoral Regiment) would need 9 LSMs. As a comparison the Jason class of the Greek Navy is about 380 ft long, with a top speed of 18 knots

==Legacy==
One LSM, ((USS|LSM-45)), survived in its original configuration until around 2010. It was in storage at Marine Station [[Camp Lejeune]] in [[Jacksonville, North Carolina]]. It was slated to become the centerpiece of the Museum of the Marine, but due to changed plans, was [[Ship breaking|scrapped]] between 2010 and 2014.((citation needed|date=January 2022))

==Light Amphibious Warship (LAW)==
As of February 2023 the US Marine Corps has proposed the purchase of 18 to 35 modern LSMs; this LSM concept was previously known as the Light Amphibious Warship (LAW).<ref name=USNI_20230214>((cite news|title=Marine Corps Requirements Call for 9 Light Amphibious Ships per Regiment |date=February 2023 |first=Mallory |last=Shelbourne |url=https://news.usni.org/2023/02/14/marine-corps-requirements-call-for-9-light-amphibious-ships-per-regiment |newspaper=USNI News |publisher=United States Naval Institute ))</ref><ref name=USNI_20230222>((cite news|title=SECNAV Del Toro 'Excited' About New Landing Ship Mediums |date=February 2023 |first=John |last=Grady |url=https://news.usni.org/2023/02/22/secnav-del-toro-excited-about-new-landing-ship-mediums |newspaper=USNI News |publisher=United States Naval Institute ))</ref>
