The Mastiff had a different configuration from the early prototypes, featuring the pusher-propeller twin-boom configuration that would become common for combat surveillance UAVs. The Mastiff was introduced in 1975, but nobody seemed interested. 

“猛犬”（Mastiffs）有一种来自早期原型的不同的配置，以推进-螺旋浆、双-吊杆为特点，成为通用战斗监视无人机（UAV）。“猛犬”（Mastiffs）在1975年被推出，但是没有人感兴趣。 
 

The lack of activity was deceptive. The Israeli military were becoming increasingly interested in battlefield UAVs, and in response IAI decided they were interested in the concept as well. Tadiran and IAI found themselves in bitter competition for military battlefield UAV contracts. 
使用率的缺乏是靠不住的。以色列军队正在逐渐地对战场无人机感兴趣，并在决定他们响应以色列飞机工业公司（IAI）中也对概念感兴趣。塔迪兰（Tadiran）公司和以色列飞机工业公司（IAI）为军用战场无人机合同发觉自己处在激烈的竞争中。

 

The Israeli military began to buy more Mastiffs, while IAI came up with a competitor with the appropriate name of "Scout" and sold it to the military as well. The Scout, which was also known as "Zahavan (Oriole)", had a similar configuration to the Mastiff, with a pusher propeller and a twin-boom tail. 
以色列军队开始购买较多的“猛犬”，虽然以色列飞机工业公司（IAI）也用“侦察兵”（Scout）的适当名字提出一个竞争者和销售它到军队。“侦察兵”，也是即是“Zahavan（金莺）”，具有同“猛犬”一个相似的配置，使用一具推进螺旋浆和一个双-吊杆尾部。 

 

During Operation Peace for Galilee (1982) where they were confronted by Syrian SAMs, which were heavily sited in Lebanon's Bekaa Valley. All 28 SAM sites in the Bekaa were destroyed, however, partly through the use of Sampson decoys to get them to reveal their presence, and partly through reconnaissance information obtained by the Mastiff and Scout UAVs. 
在“加里利和平”（Peace for Galilee）（1982年）军事行动期间，在那里他们面对叙利亚的防空导弹（SAM），大量地位于黎巴嫩的贝卡（Bekaa）谷。然而，贝卡（Bekaa）的所有28个防空导弹（SAM）位置被摧毁，部分经过使用Sampson诱饵无人机去使他们显露他们的存在，和部分经过由“猛犬”和“侦察兵”无人机获得的侦察信息。

 

After consolidating production of the Mastiff and Scout, the Malat company continued to sell them in slightly refined versions for over a decade. Both aircraft have fixed landing gear and are generally operated from runways, performing short landings using an arresting-wire hook, though they may be launched using a hydraulic catapult off the back of a truck, and recovered by a net. They both carry imaging sensors in a turret underneath the fuselage. 
在巩固“猛犬”和“侦察兵”的生产之后，在十年以来马拉特（Malat）公司继续销售他们轻微细化的型号。两者的飞行器装有固定起落架并且通常从跑道操作，短降落性能使用一个拦阻-金属线钩，尽管他们能从卡车后部使用一部液压弹射器起飞和采用拦阻网回收。它们两者都在机身的下面携带一套装在转塔中的图像传感器。 

The Mastiff and Scout remained in service with the Israeli Army until the early 1990s, when they were replaced by the Malat Searcher, also known as the "Meyromit (High Flier)". The Searcher looks almost identical to the Scout and Pioneer, but is scaled up, and in fact is well over twice the size of the Scout.

当他们被马拉特（Malat）“搜索者”代替了的时候，也即是“Meyromit（高飞者，High Flier）”，“猛犬”和“侦察兵”保持在以色列陆军中服役直到1990年。“搜索者”几乎看起来与“侦察兵”和先锋相同，但是比例增大，而且事实上大大超过“侦察兵”尺寸的两倍。
