Ranger-class patrol ship

The Ranger-class served the United Nations Space Command (UNSC) as patrol ships during the Interplanetary Era. Seventy-eight patrol ships were commissioned in six groups: 24 of the Ranger group, 24 of the Republic group, 6 of the Rival group, 12 of the Roman group, 8 of the Rubicon group, and 4 of the Rheasilvia group. The Ranger-class and its five subclasses were active from 2173 until 2330. 
==History==
===Development and construction===
===Service===
==Design==
The Ranger patrol ships were larger than most of the predecessors, measuring some 317 meters in length. The bulk of each ship contained potent sensor systems, powerful engines, and lethal weaponry. The Ranger design sported thirty-two M7G Vanguard anti-ship missiles and 108 Boreas point defense missiles, in four and six missile pods respectively. With a crew of 70, a Ranger patrol ship was expected to be capable of lengthy deployments throughout the system, with sufficient supplies on board for six months should that be necessitated. 
Twenty-three patrol ships of the original Ranger group were decommissioned by 2242; the Rampart II remained in service until 2259, and only as an ODST training ship following conversion work in 2239. 
===Republic-class===
The Republic patrol ships entered service from 2176 to 2178. Outwardly equivalent to Ranger patrol ships in all but name, the interior of the Republic design was substantially different, having been modified to accommodate a larger reactor and smaller engineering section. The last of the Republic-class patrol ships were decommissioned in 2256. 
===Rival-class===
The Rival patrol ships entered service from 2179 to 2182. Much like the later Rheasilvia group, the six patrol ships of the Rival-class were built for long-range tours of the outer system. Rival patrol ships reduced crews to 45 personnel, added more amenities and comforts, and carried enough supplies to last 18 months. The Rival-class was decommissioned from the late 2290s to the first decade of the next century, with the Rifleman being retired in 2309. 
===Roman-class===
The Roman patrol ships entered service from 2179 to 2181. The Roman group adhered to the modifications of the Republic group, with the addition of an enlarged amenities suite borrowed from the Rival group. The last of the Romans, the Robust, was retired in 2307. 
===Rubicon-class===
The Rubicon patrol ships entered service from 2182 to 2185. The Rubicon modifications were perhaps the most considerable of any subclass. Changes included: the addition of eight crewmembers and a security team of 16 marines; enlargement of the ship's weapons lockers, infirmary, and brig; and reduction of onboard supplies to enough for a month. The Rubicon patrol ships were deployed exclusively to the Jovian Trojans, with four members of the class assigned to each camp. The class was slated for decommissioning after the turn of the century, with the Rushmore being the last to retired in 2318. 
===Rheasilvia-class===
The Rheasilvia patrol ships entered service from 2185 to 2191. Like the earlier Rival-class, the Rheasilvia-class were built for outer system patrol. The Rhapsody, Rheasilvia, and Rhineland were decommissioned in the 2320s; the Rhiannon, last of the Ranger patrol ships, was decommissioned in 2330.

===UNSC Rampart II===
The UNSC Rampart II was commissioned in 2175 and remained in use as a patrol ship until 2239, when it was disarmed and converted for use as an ODST training platform. For the next two decades, the Rampart II was used extensively for ship boarding action simulations. The ex-patrol ship was decommissioned in 2259 and sold for scrap. 
===UNSC Rhiannon===
The UNSC Rhiannon was commissioned in 2190. The patrol ship was named for the Rhiannon complex on Europa, home to a major shipbuilder, a massive industrial sprawl, and the site of a historic ODST assault. The Rhiannon spent the next fourteen decades conducting patrol operations in the outer system, and was well-known by its end of service in 2330. The patrol ship was the last Ranger in service before its decommissioning. The Rhiannon was demilitarized and sold to the Europan community it was named for and was installed as a museum ship there. 
===UNSC Rhineland===
The UNSC Rhineland was commissioned in 2192. The patrol ship spent the majority of the next 136 years in the outer system, especially in the Saturnian Space and beyond. The Rhineland was decommissioned in 2328.
