As such, the inherited and new-build vessels were all assigned a range of 100 numbers to fill, that was limited to that specific class. When a new class was built, it would receive the next block of 100 numbers. If a class exceeded 100 units built, it would be assigned another block of 100 numbers, often seperated from the original block. This created gaps within the overall numbering sequence, appearing to suggest there were more starships within the Star Fleet than actually existed. (This was also an advantage for ‘black ops’ ships, that could be assigned a number in a non-related class and sneak by extreme scrutiny of any watchdog or intelligence groups monitoring Star Fleet’s construction programs.)&amp;lt;br&amp;gt;&lt;/div&gt;&lt;/td&gt;&lt;td class=&quot;diff-marker&quot; data-marker=&quot;+&quot;&gt;&lt;/td&gt;&lt;td style=&quot;color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt; &lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

==2.1.10 Starfleet Registry Numbers==&lt;br /&gt;
	The method in which the two incarnations of Starfleet (that of the United Earth and of the United Federation of Planets) registers its ships has changed three times. The UESF, upon its formation, registered vessels numerically following the classification codes (ex: EC-19) in chronological order of the ships built in that classification code, as per the traditions of one of its preceding services, the United States Navy. That is, when a vessel was first commissioned into service, it assumed the next available hull number for that classification type (ex: heavy escorts).
