The Delilah was originally developed as an airborne expandable decoy. It’s principal mission were deception and intelligence gathering. Since the development of Delilah, the Delilah has been developed into an air-launched stand-off cruise missile. The missile has a cylindrical fuselage, fixed short-span tapered wings and cruciform tailfin.
Delilah Cruise Missile
The Delilah missile is a cruise missile developed in Israel by Israel Military Industries (IMI). The missile is designed to target moving and re-locatable targets with a CEP of 1 metre (3 ft 3 in). Unlike a typical cruise missile, which is locked onto a pre-programmed target prior to launch, the Delilah missile is touted by the Israeli military as being able to “patrol” and surveil an area before a remote navigator identifies the specific target of the attack.
It can be carried on MAU-12 under wing pylons and launched any number of aircraft including F-16, F-15 and F-35 fifth-gen fighter aircraft. The Delilah is currently operated by Israeli Air Force and Vietnam Air Force is allegedly negotiating with Israel to procure Dalilah Cruise Missile and integrate with Su-30MK2V aircraft.
The Delilah-GL is a ground-launched version of the Delilah cruise missile, that has a range of 250 km. Israel Military Industries said the flight range of the Delilah-GL — a converted air-launched missile — is 250 kilometers, while Israeli defense officials put the range at more than 300 kilometers.
The missile carries a 30-kilogram high-explosive warhead, but Israel Military Industries otherwise declined to detail the missile’s payload capabilities. The ground-launched Delilah is reported to include systems able to pinpoint targets at distances up to 16 kilometers and can “loiter” over target areas. The missile can also double as an unmanned reconnaissance vehicle.
The Delilah is an air-launched stand-off missile and cruise missile with a range of 250 km and can be fitted with a variety of warheads which can be targeted on both land and sea targets.
Israel is also looking at converting two other weapons systems into land-attack missiles based on Delilah with ranges of up to 300 kilometers (Alon Ben-David, Jane’s Defense Weekly, June 16).
The Delilah anti-radiation attack drone was configured after the US MQM-74 Chukar aerial target.
Israel has developed its first surface-to-surface cruise missile based on Delilah, but details of its full payload potential remain a secret, according to the June 16 issue of Jane’s Defense Weekly (see GSN, Oct. 14, 2003).
The military breakthrough comes after the United States twice refused to sell Tomahawk land-attack missiles to Israel, the Jerusalem Post reported yesterday (Douglas Davis, Jerusalem Post, June 8).
How Delilah Works?
the Delilah is almost identical to a typical air-to-ground missile. The front section includes the homing parts, which in the first models were televisional. Thus, the head of the missile includes an antenna for general guidance towards its target. The next section holds the various electronic parts including guidance systems and flight control. The part behind this holds the warhead and fuel supply. The final section is made up of a jet engine capable of producing 165 pounds of thrust and the control surfaces that turn the missile towards its target.
Examining the technical data alone raises the question of why the Delilah is considered such an important missile. After all, there are missiles capable of flying further and faster and carrying warheads many times larger which are available on the global weapons market. The answer lies in the fact that the Delilah is seen more as a “loitering missile” than a cruise missile.
In general typical air-to-ground missiles are launched in the general direction of their target. A navigational system (such as GPS) takes them to the spot where intelligence indicates that the target lies. If the missile is autonomous (“fire and forget”) then the plane that launched it can simply leave. The missile flies towards the target. When it identifies it, it strikes it with the help of its final guidance system. When the target is not where it is expected to be, the missile is simply written off. An example of this sort of weapon is the US Tomahawk missile, at least in its early models.
When a missile is fitted with an electro-optic guidance system, it broadcasts an image of what is in front of it, back to the aircraft that launched it. The image from the homing device is shown on a special screen in the cockpit, usually facing the navigator’s chair in a two-seater aircraft. The navigator can send the missile instructions, and make small changes in its flight path. However, these changes can only take pace during a relatively short period of time, and are comparatively minor. From the moment that the missile begins its final approach, no changes can be made. The result is that although he has some control, the navigator is actually very limited. If a missile approaches a target, which at the last minute turns out to be moving, or the wrong target altogether, then the missile misses. Thus, there have been many events like the one in Yugoslavia in 1999 when an electro-optic bomb launched from a US combat airplane was launched at a bridge. Seconds before impact, a passenger train reached the bridge and all the navigator could do was watch in horror, knowing that many civilians would be killed. It is here that the Delilah’s unique ability enters the picture.
The Delilah’s operation is similar to what is described above; it, too, possesses a “Man in the Loop” mechanism, where the navigator controls the final direction of the missile. However, in the case of the Delilah there’s a key difference: as the missile makes the final approach, if the target has moved or if there’s a need to cancel the attack (for example, if civilians are spotted near the target), all the navigator needs to do is press a button in the cockpit which instructs the missile to abort its approach and return to linger. Thus, situations in which a missile is wasted on a target that has disappeared, or in which civilians are accidentally killed can be prevented. In the same way the use of a missile on a target that has already been destroyed can be prevented, saving valuable ammunition.
This is not the only value in the Delilah missile’s ability to linger. One can imagine a situation in which the target’s precise location is not known with any certainty, for example if it is a portable anti-aircraft launcher or land-land missile launcher. In this case the Delilah can be launched in the general direction of the target, based on intelligence reports. The missile would fly in the direction of the target, all the while surveying the territory with its homing equipment. The image appears in the cockpit, the Delilah serving effectively as a homing UAV. The Delilah patrols above the territory searching for its target. The missile’s long range can be exchanged for a prolonged stay in the air above the target. When the navigator identifies the target, or what is thought to be the target, he instructs the missile to fly towards it. If he has identified it correctly then the missile is directed to attack it. If he has not found the target then the missile is instructed to abort its approach and return to searching.
The Delilah missile’s ability to both loiter and carry out repeated passes makes it the ideal weapon for attacking mobile sites like rocket launches. Everyone recalls the difficulty the US Air Force faced during the 1992 Gulf War when it attempted to locate and destroy the Iraqi “Al-Hussein” rocket launcher that was used to fire at Israel and Saudi Arabia. The Americans knew roughly where the rockets were being launched from but had difficulty locating the launchers themselves. As a result fighter planes were sent for long patrols over western Iraq every night. On many occasions the Americans identified the point where the missile was launched from, but by the time a counter-strike had been arranged the missile launcher had left the scene. It’s in these sorts of operational profile that the Delilah performs best, perhaps better than any other weapons system. In these cases the Delilah can be launched towards the area intelligence expects the missiles to be launched from. The Delilah will fly above the area and search for missile launchers. When a launcher is identified, it will be immediately struck by the missile. If it’s discovered that the target has not been identified correctly, for example if it’s a dummy launcher or another vehicle that looks like a launcher (such as a petrol tanker), the missile receives the instructions to end its approach and continue to search for the real target.
“The Delilah is a system that can strike very precisely at critical, sensitive points from a great distance”, explains Brigadier General (reserve) Arieh Mizrachi, who was once CEO of IMI.”If we want to attack a command bunker, for example, and we know where it is situated and exactly which window we need to hit then we can do it. We can always make another approach and place the missile exactly where we want it. The extreme precision of the missile makes it possible for us to paralyze the enemy by striking their critical point. For example, if we send the missile through a window of a division’s control center, then no one will be left to give orders, and we’ll have silenced the whole division. It’s important to understand that the target does not need to be a large command center. The ‘Delilah’ lets us strike at the brain of the enemy, even if it’s a small mobile target like a command armored personnel carrier. Similarly, we can strike at a ship’s command center without needing to sink the whole ship. This holds true for many other kinds of target like airports, logistics centers and so on. The moment we identify the critical point, the Delilah lets us hit it”.
“The training needed to operate the Delilah lasts a few months, and because of its complex capabilities, not everyone successfully completes it”, explains First Lieutenant A., an F-16D navigator in the “Scorpion” Squadron who is trained on the Delilah. “The training process is long, complex and challenging. You start with simple scenarios, hitting a large target in open space, and advance to small targets that are located in densely populated areas”.
“Despite the intense cooperation between the pilot and the navigator, the fact remains that the missile is operated from the navigator’s cockpit. In the first stage you launch the missile and it flies towards the target you’ve given it. Later in the flight, you take control of the missile and direct it wherever you want. If you need to, you can press a button and the missile will loiter. The role of the pilot is to tell me when I’ve reach the point where I need to tell the missile to fly, and I can no longer tell it to continue to loiter”.
“Even though you are not physically in the same place as the missile, and in fact are far away, the whole time you feel that you are part of it. The fact that you can fly the missile wherever you want, whilst you yourself fly to an area that is not under threat, gives you safety”.
Israel, which released footage of the Pantsir-S1 system being hit, said it launched the attack after Iranian forces fired 20 rockets toward the Golan Heights on Wednesday, some of which were shot down.
It could be that its radar was turned off to avoid anti-radiation missiles – it was most likely hit by a Delilah anti-radar cruise missile – or that the Syrian operators simply bungled the incident.Mikhail Khodorenok, a retired Russian colonel, also told RT
Whatever the reason the Pantsir-S1 took a direct hit, it wasn’t good advertising for the Russian system, as Moscow heavily depends on foreign military sales to boost its flagging economy.
On May 9, 2018, the Quds force, a special force wing of the Iranian Revolutionary Guard, stationed in Syria, shot 20 rockets towards IDF posts in the Golan Heights. The IDF intercepted four of the rockets, preventing casualties and damage. This is the first time that Iranian forces have directly fired at Israeli troops.
In response, in the night on May 10, IDF fighter jets (mainly F-16I Sufa aircraft according to most sources even though the official IAF website’s release on the attack shows also a file photo of an F-15I) struck several military targets in Syria that belonged to Iran’s Quds force. “The IDF’s wide-scale attack included Iranian intelligence sites, the Quds force logistics headquarters, an Iranian military compound in Syria, observation and military posts, et cetera. In spite of a warning from Israel, Syrian aerial defense forces fired towards the IAF aircraft as they conducted the strikes. In response, the IAF targeted several aerial interception systems (SA5, SA2, SA22, SA17) which belong to the Syrian Armed Forces. All of the IDF’s fighter jets returned to their bases safely.”
Among the targets hit by the Israeli combat planes there is also Pantsir-S1 and Buk-M2E as shown in the following footage.

The transportable SAM system are advertised to intercept cruise missiles which has proven so far lame ducks. Russian S-300 and S-400 stationed in Syria are at the mercy of Israeli Air Force.
