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 3.236.0.0/16 has been blocked (disabled) by ‪ST47‬ 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. To prevent abuse, web hosts may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host 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 web host'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 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 (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.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and they 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 06:21, 30 September 2026.

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.

The '''David Taylor Model Basin''' ('''DTMB''') is one of the largest [[ship model basin]]s—test facilities for the development of ship design—in the world. DTMB is a field activity of the [[Carderock Division of the Naval Surface Warfare Center]].

==History==
In 1896, [[David Watson Taylor]] designed and supervised construction of the [[Washington Navy Yard]]'s Experimental Model Basin which was at that time the best facility in the world.  That facility was a significant design testing capability before, during, and after [[World War I]].  Inadequacies in that facility led the navy to look for a new model capability.<ref>((cite web |url=https://mht.maryland.gov/secure/medusa/PDF/NR_PDFs/NR-936.pdf |title=National Register of Historic Places Registration: David Taylor Model Basin |date=July 1984 |access-date=1 January 2016 |first=David K. |last=Allison |publisher=Maryland Historical Trust ))</ref>

The new navy modeling facility—named for David Taylor—was built in 1939 in today's community of [[Carderock, Maryland|Carderock]] just west of [[Bethesda, Maryland]] in [[Montgomery County, Maryland|Montgomery County]]. The Carderock facility contains multiple test basins (towing tanks for models) designed for a variety of testing capabilities.  DTMB has strongly influenced naval architecture for 70 years.((Citation needed|date=April 2023))

==Technical capabilities==
Three adjoining sections comprise the Shallow Water Basin: deep water, shallow water, and a ((mono|J))-shaped [[turning basin]] used for steering maneuvers.  Its carriage can provide speeds up to 18 [[knot (unit)|knots]].

The Deep Water Basin wavemaker located along the side, and a [[wave]] absorbing beach at the other. The wavemaker consists of 216 electro-mechanical panels called wave boards.<ref>((Cite web|title=New MASK Unveiled - Magazines|url=https://magazines.marinelink.com/Magazines/MarineTechnology/201403/content/new-mask-unveiled-465342|access-date=27 December 2021|website=magazines.marinelink.com))</ref> This capability allows modeling of regular or irregular sea states. Located behind a movable section of the beach is a fitting out [[dry dock]]. Its carriage can provide speeds up to 20 knots.

The High-Speed Basin comprises two adjoining sections: a deep water section and a shallow water section. Wavemaking capability exists in this basin, and there are three large underwater viewing windows at different elevations which are set into the wall about mid-length. The high-speed carriages can provide complex motions for the model at speeds up to 50 knots.

==Computing==
The David Taylor Model Basin was an early adopter of computers, and an active site for computer technology.  Represented by [[Betty Holberton]], it was one of three government agencies present at the 1959 meeting where the computer language [[COBOL]] was created.<ref>((cite journal |last=Sammet |first=Jean |author-link=Jean Sammet |title=The Early History of COBOL |journal=ACM SIGPLAN Notices |volume=13 |issue=8 |pages=121–161 |publisher=Association for Computing Machinery |date=1978 |url=http://portal.acm.org/citation.cfm?id=1198367 |doi=10.1145/960118.808378 |s2cid=10743643 |access-date=4 April 2023 ))</ref>
