Large, Slow, And Non-Stealthy Is No Way To Go Through Life

There are many naval observers who espouse the idea of balloons of some type (aerostats, for example) as a means of providing long range surveillance.  ComNavOps has scoffed at those ideas as being devoid of realistic usefulness and, worse, a detriment to surrounding forces due to being easily detected.  Well, here’s further evidence of the impracticality of such aerostats.  Israel, who famously implemented the Sky Dew aerostat system amid much fanfare and proclamations of miraculous capabilities, is now leaning towards abandoning the entire concept due to unaffordable repair costs, questionable usefulness, and demonstrated vulnerabilities following a Hezbollah suicide drone strike that hit the balloon and rendered it inoperable (see, “You Had One Job”).
 

Israeli defense officials are reevaluating the future of the military’s Sky Dew project, a high-altitude balloon system designed for aerial threat detection, following a series of setbacks including weather damage and an attack by the Hezbollah terror group.[1]
 
In light of these repeated setbacks, defense officials are now seriously considering terminating the project. The vulnerability of the system, its high costs, and the excessive time required for repairs have all factored into this revaluation of a program that has already consumed millions in defense spending.[1]

It’s not just enemy actions that threaten the aerostat;  weather is also a threat.
 

… severe weather had rendered the system inoperable months earlier.  After a protracted repair process, the balloon was redeployed in January [2024] … [1]

Setting aside the actual performance failure of Sky Dew in failing to detect a drone which was its exact intended function, the aerostat has been found to be vulnerable to weather and highly susceptible to enemy attack.  Is this surprising?  No!  Any large, slow (non-mobile, in this case), non-stealthy object is easily detected and simply waiting for the enemy to get around to it on their ‘items to destroy at leisure’ checklist.
 
So, what does this mean for us?
 
This is yet another example demonstrating that large, slow, and non-stealthy aircraft such as AWACS, E-2 Hawkeye, P-8 Poseidon, all large non-stealthy UAVs (Predator, Global Hawk, Reaper and the like), etc. are simply not survivable on the modern battlefield.  It doesn’t matter whether it’s a balloon tethered to a ship or a P-8 Poseidon lumbering around looking for things, large, slow, and non-stealthy is simply not viable.
