ガンダム7号機
型號：RX-78-7
第7號機最初是作為吉姆的基本機體存在，但後來進行了改裝。在設計階段，一年戰爭結束時，它只是基本框架的狀態，但到宇宙世紀0081年已經完工。
由於在設計階段就考慮了全副武裝等選擇性系統，因此機體各處都設有安裝點和各種介面的選擇性端口。裝備增加裝甲（第一裝甲）的話，就成為全武裝鋼彈7號機，再安裝第二裝甲就成為重裝全武裝鋼彈。機體本體上施以磁性塗層，裝備了試作型的全方位監視器等，具有鋼彈NT-1級的機體性能。背包的主推進器有6個，通過將其配置為RX-78型的結構，確保了高推進力和可靠性，同時還作為與胸部單元整合的方塊結構，充當各種附加裝備的可插拔端子。
フルアーマーガンダム7号機（フルアーマー3号機）
型號：FA-78-3
這是在機械設計企劃「M-MSV」中設定，由大河原邦男設計（首次亮相於『SD CLUB』第14號），在遊戲『機動戰士鋼彈戰紀』中由加藤寶島重新設計。由於它是繼全武裝鋼彈和重裝鋼彈之後的型號，也被稱為「全武裝3號機」。
從一開始就考慮了全武裝等選擇性系統的鋼彈第7號機，裝上了增加裝甲（第一裝甲）的狀態。設計概念從FSWS計劃一開始就更進一步，更加考慮與基礎機的匹配，增加裝甲部分也裝備了次發電機（在重新設計的模型的說明中表示為「內置次發電機」），並添加了大量的推進器，以確保即使在全副武裝狀態下也能成為一個「完整的機動戰士」。此外，通過在機體的質量中心即腰部（臀部）裝備作為AMBAC（機體姿態控制）作動肢的尾部穩定器，極大地改善了機體的加速性。
重装フルアーマーガンダム
型號：HFA-78-3 / FHA-78-3
這是在全武裝鋼彈7號機的基礎上裝備了進一步的選擇性裝甲（第二裝甲）的狀態，其設計思想被視為接近機動裝甲和戰艦。雖然裝備了高輸出的推進器，但它不擅長機動，並且完全不適合機動戰士之間的近戰。
在實際運用中，使用本規格的推進器可以在短時間內快速移動到前線，同時使用像戰艦一樣的巨型光束炮進行遠距離威嚇和攻擊。在中距離戰鬥中，會拆除第二裝甲，轉而使用全武裝鋼彈7號機進行戰鬥（但背部的光束炮不會裝備）。在近距離戰鬥中，會移除第一裝甲的部分，轉而進行完全的光束步槍和光束刀格鬥戰。
儘管在一年戰爭時期被認為無法實現這種技術水平，但包括鋼彈7號機本體和全武裝鋼彈7號機在內，於宇宙世紀0081年完成，並參與實戰。
イフリート・ナハト
Model Number: MS-08TX/N
The Efreet Nacht is a modified version of the close-combat mobile suit MS-08TX Efreet, designed specifically for stealth operations and night combat, as its name suggests ("nacht" being German for "night"). It is equipped with a powerful jamming system capable of disrupting radar and mobile suit sensors, making it highly effective in covert missions.
To enhance its stealth properties, the air ducts on the Efreet Nacht's chest were removed, and it was outfitted with a new backpack featuring retractable thrusters. Additionally, twin thruster units were added to its legs, further improving its thrust and mobility. To avoid heat detection, the Efreet Nacht's primary weapon was changed from the heat saber to a ninjato-style physical sword known as the Cold Blade. For ranged combat, it is equipped with four Cold Kunai for throwing, as well as a three-barrel Gatling gun concealed in the left forearm. This combination of weapons and stealth features makes the Efreet Nacht a formidable opponent in night operations.
ジーライン 基本フレーム
The RX-81, unlike the mass-produced GM series that prioritized productivity and thus had considerably lower specifications than the RX-78-2 Gundam, was designed to retain the high specifications of the Gundam. Additionally, the RX-81's design incorporates the FSWS (Full-armor System and Weapon System), which allows for an increased variety of weapons and armor configurations, resulting in multiple forms that the mobile suit can change into depending on the situation. The mobile suit's backpacks can be swapped out as needed, with two thrusters for ground operations and six for space, allowing it to adapt to different combat environments effectively.
ジーライン スタンダードアーマー
Model Number: RX-81ST
The RX-81ST G-Line Standard Armor is the standard configuration of the RX-81 G-Line, designed to be highly versatile and usable in all ranges of combat. This configuration allows the mobile suit to adapt to various battlefield conditions effectively. When additional firepower is needed, the RX-81ST can be equipped with extra armaments on its backpack, enhancing its attack capabilities. In its fully equipped state, the suit features a backpack with two additional medium stabilizers, which serve to extend the suit's operational time, making it suitable for prolonged missions.
ジーライン ライトアーマー
Model Number: RX-81LA
Out of the three equipment sets, the RX-81LA Light Armor configuration is the lightest, offering low defense but the highest level of mobility. This high-performance mobile suit is primarily deployed by ace pilots who require exceptional speed and maneuverability in combat. To achieve this, the Light Armor RX-81's armor is made very thin to reduce weight, and short-range combat armaments have been removed to optimize the thrust-to-weight ratio and increase overall speed.
The backpack of the RX-81LA mounts a large stabilizer, further enhancing its high-mobility performance. For long-range engagements, it is equipped with a head-mounted sensor unit. Additionally, the suit can be fitted with various optional weapons, including missile launchers, an assault cannon, or gatling smasher guns, making it versatile in different combat scenarios.
