大力神 IIIB | KH-8 8

描述

Titan IIIB was the collective name for a number of derivatives of the Titan II ICBM and Titan III launch vehicle, modified by the addition of an Agena upper stage. It consisted of four separate rockets. The Titan 23B was a basic Titan II with an Agena upper stage, and the Titan 24B was the same concept, but using the slightly enlarged Titan IIIM rocket as the base. The Titan 33B was a Titan 23B with the Agena (which had a smaller diameter than the Titan) enclosed in an enlarged fairing, in order to allow larger payloads to be launched. The final member of the Titan IIIB family was the Titan 34B which was a Titan 24B with the larger fairing used on the Titan 33B.

大力神 IIIB（Titan IIIB）是大力神 II 洲际弹道导弹与大力神 III 运载火箭多种衍生型的统称，通过加装阿金纳（Agena）上面级改进而来，由四型独立火箭组成。Titan 23B 是带阿金纳上面级的基本型大力神 II；Titan 24B 概念相同，但以略放大的大力神 IIIM 为基座；Titan 33B 是在 Titan 23B 基础上，将直径小于大力神的阿金纳包裹于加大的整流罩内，以发射更大载荷；大力神 IIIB 家族的最终成员 Titan 34B 则是采用 Titan 33B 加大整流罩的 Titan 24B。
