Most UNSC military vessels, such as theUNSC Infinity, are armored with Titanium-A plating.
大部分UNSC军用舰艇，比如UNSC无尽号，装备有A型钛合金装甲。
Titanium-A armor is the most common form ofbattle plating used by the UNSC on its warships. It is composed of high-gradeTitanium-50 that is specially strengthened at the molecular level, whichimplies alloying with other elements. It is usually greyish in color. Followingthe Human-Covenant War, some UNSC military vessels received energy shielding toallow the ships to absorb more damage. Like the Magnetic Accelerator Cannon,Titanium-A armor plating saw advances and widespread use due to theInsurrection.
A型钛合金装甲是被UNSC使用在其战舰上最多的一种战斗装甲。它由在分子层面特别强化的优质钛-50（钛的一种同位素）组成，这暗示还加入了其他元素。它一般呈现灰色。在人类——星盟战争之后，一些UNSC军用舰艇接收了能量护盾让它们承受更多的伤害。和MAC炮一样，由于叛军，A型钛合金装甲见证了其进步和广泛使用。

Titanium-A has numerous uses throughout theUNSC due largely to titanium being lightweight and extremely strong, with ahigh tolerance to heat. Its primary use is armor for ships. Typically, as muchas one-third of a standard UNSC military vessel's mass is the Titanium-Aplating. UNSC frigates have sixty centimeters of plating on their hull, UNSCdestroyers have up to two meters of plating and UNSC carriers have thirty-sixcentimeters of Titanium-A plating. Marathon-class heavy cruisers have 4775px-thick layers of Titanium-A armor, allowing them to sustain far greaterdamage. D77-TC Pelicans and GA-TL1 Longswords are both covered in Titanium-Aarmor to provide additional protection in dogfights. Slipstream space probesare almost pure Titanium-A armor to allow them to survive the stresses offrequent slipspace entries and exits. Long Range Stealth Orbital Insertion Podsare given additional Titanium-A plating to allow the pods to be launched fromslipspace Refit stations and construction platforms, such as Station Delphi,are essentially slabs of Titanium-A armor plating.
A型钛合金装甲在UNSC中被广泛使用很大程度上是因为钛的密度低、强度高、耐高温。它主要作为舰船的装甲。通常，一艘标准的UNSC军舰大约三分之一的质量就是A型钛合金装甲带来的。UNSC护卫舰船身拥有60厘米厚的装甲，UNSC驱逐舰拥有厚达2米的装甲，UNSC航母拥有36厘米厚的A型钛合金装甲。马拉松级重型巡洋舰拥有191厘米厚的A型钛合金装甲层，使它们可以承受更严重的损伤。D77-TC鹈鹕号和GA-TL1长剑截击机都覆盖有A型钛合金装甲在狗斗中提供额外保护。断层空间探测器几乎就是一块A型钛合金装甲，使得它们能承受频繁进出断层空间的压力。长程隐身轨道空降舱配备了额外的A型钛合金装甲来让它们能够从断层空间整修站和建造平台上发射，比如德尔福空间站，完全就是一块块A型钛合金装甲板。
The UNSC uses Titanium-A for constructionof military bases as well, to make them less susceptible to destruction.Underground facilities such as HIGHCOM Facility Bravo-6, CASTLE Baseand Camp Hathcock used Titanium-A armor in their superstructures. Even lockersused by UNSC personnel are reinforced with a centimeter of Titanium-A armorplating. Eridanus Secundus, a United Rebel Front asteroid base located in theEridanus system, was reinforced with a layer of Titanium-A armor which alsohelps deflect UNSC and Covenant sensors.
UNSC也使用A型钛合金建造军事基地，提高它们的抗打击能力。地下设施比如最高统帅部B-6设施（HIGHCOM Facility Bravo-6）、城堡基地和哈斯考克营地使用A型钛合金作为上层结构。甚至UNSC人员的锁都是用一厘米厚的A型钛合金装甲加强的。波江座塞肯多斯（Secundus），一处位于波江座系统的联合抵抗阵线的小行星基地，也由一层A型钛合金装甲加强，并帮助其躲避了UNSC和星盟的探测器。

The UNSC Grafton is destroyed by a singleenergy projector shot.
UNSC格拉夫顿号被能量投射器一击击毁。
Prior to the Human-Covenant War, a singleMagnetic Accelerator Cannon slug was capable of penetrating any vessel'sTitanium-A armor plating. The armor took a newfound importance after thebeginning of the Human-Covenant War: to contend with the Covenant's plasmaweaponry, humans needed armor that would withstand the heat of the directedplasma. Despite its strength and resistance to heat, however, the Titanium-Aplating is usually boiled away within seconds on contact with Covenant plasmatorpedoes, and does not effectively dissipate the plasma. Energy projectors areable to pierce dozens of centimeters with relative ease. Pulse laser turretscan reduce the hull of a Paris-class heavy frigate to about four centimeters ina single hit. Even energy swords can do significant damage to Titanium-A armor.During the Fall of Reach, the UNSC Grafton was destroyed by a single shot fromthe Long Night of Solace's energy projector. Despite being armored with thestronger Titanium-A3 armor, the UNSC Infinity's hull was pierced by a Covenantmercenary space station's glassing cannon. After three hits from the cannon,the Infinity was nearly destroyed. However, the UNSC Savannah was able to holdits own for a while against the much larger Ardent Prayer, despite beingseverely outgunned.
在人类——星盟战争之前，MAC炮一发就能穿透任何舰艇的A型钛合金装甲。这种装甲在人类——星盟战争开始之后起到了一个新作用：为了承受星盟等离子武器攻击，人类需要能够承受等离子体直接打击带来的高温的装甲。尽管它强度高、耐高温，但是，A型钛合金装甲经常在与星盟等离子鱼雷接触几秒内被蒸发掉，并且不能有效地使等离子体消散。能量投射器能够轻易穿透几十厘米厚的该型装甲。脉冲激光炮塔一发可以打进巴黎级重型护卫舰船身大约4厘米处。甚至能量剑都可以对A型钛合金装甲造成显著伤害。在致远星战役期间，UNSC格拉夫顿号被漫漫长夜号的能量投射器一击击沉。尽管装备了强度更高的A3型钛合金装甲，UNSC无尽号的船身也被星盟雇佣兵空间站的玻璃化加农炮（名字很诡异，但是发射的应该还是等离子）击穿。在被三次击中后，无尽号险些毁于一旦。但是UNSC萨瓦娜号却可以独自迎击更大的热情祈祷号一段时间，尽管火力严重不足。
Titanium-A armor plating can be layeredwith tungsten for a radiation absorption rating of 5 and presumably grantgreater protection against plasma weaponry. Unlike the Covenant's nanolaminatehull plating, Titanium-A plating is not effective during direct collisions withother vessels. After a direct collision with a CPV-class heavy destroyer, theUNSC Spirit of Fire was heavily damaged, while the destroyer was seeminglyunharmed. When the destroyer UNSC Iroquois collided with a Covenant stealthship, the Iroquois lost all two meters of Titanium-A plating, although it didsucceed to disabling the Covenant vessel.
A型钛合金装甲可以添加一层钨来提供5级辐射吸收，还可能赋予对等离子武器更强的防御。不同于星盟纳米层船体外壳，A型钛合金在和其他船舰的直接碰撞中并不有效。在和一艘CPV级重型驱逐舰碰撞之后，UNSC火灵号严重受损，然而那艘驱逐舰看起来就是洒洒水啦。当UNSC驱逐舰易洛魁号和一艘星盟隐身飞船碰撞时，虽然它成功使星盟飞船丧失战斗力，但是易洛魁号失去了2米厚的A型钛合金装甲。
Titanium-A3 armor
A3型钛合金装甲
Titanium-A3 is a variant of Titanium-Abattle plate developed by ONI's Materials Group. Like Titanium-A, it ischemically altered on the molecular level to produce a stronger plate for shiphulls. It has only been noted to be used on the UNSC Infinity, whose hull iscomposed of 4.9-meter-thick Titanium-A3 battleplate.
A3型钛合金是A型钛合金战斗装甲的一个变种，有ONI材料集团研发。与A型钛合金类似，它也在分子层面进行化学变化为船身提供更强的板材。目前它仅被注意到使用在UNSC无尽号上，其船身由4.9米厚的A3型钛合金战斗装甲组成。
（不过我们老师似乎说过金属内部不存在分子啊……）
