The awsomeness of this.

Thanks folks!

Jeff: Very cool. Was that delta-winged pod in the Revell kit a 'real world' development?

Kosher Hustler - the B-58i Ariyyáhu (Part 4)

The Israeli Hustlers went through a series of incremental upgrades and equipment additions with no two aircraft ever being quite to the same standard at any given time. The B-58i was not ideal for low-level operations. In compensation, however, the afterburners were rarely needed which extended range (useful for the sometimes circuitous paths plotted out for planned missions).

Most of the IDF's equipment additions related to countermeasures -- electronic or decoys. The B-58A's original aft wing root stub pylon was adapted to carry defensive Shafrir-3M air-to-air missiles. One B-58i feature that no amount of ECM could camouflage was the smoke trails left by the GE J79 engines. But IAI had a potential solution stemming from its stalled Kurnass 2000 program -- replace the smokey J79s with new Pratt & Whitney PW1120s.

IAI proposed that four aircraft be re-engined [1] while, at the same time standardizing upgrades and adding a few new ones. The most noticeable was the addition of LARC, the Low-Altitude Ride Control system adapted from the US B-1A bomber. Less obvious was the Elta EL/M-2032 radar with superior surface target detection and mapping compared with the Elta EL/M-2021B set originally installed.

A separate program had been initiated to improve the Ariyyáhu's primary weapon. The program -- dubbed Project Othniyel ( עָתְנִיאֵל or 'Strength of God') -- took on extra urgency in 2003 when the International Atomic Energy Agency reported undeclared enrichment and reprocessing of nuclear material in Iran. The aim of the weapon program was to create a percision-guided ground-penetrating bomb while, at the same time, providing B-58i crews with a greater chance at survival.

The terms of Project Othniyel gave the development team at Rafael two imperiatives. The first was that a stand-off missile was required in place of a free-fall bomb. The second was that guidance for the weapon could not rely on airborne designators if the survival of the Ariyyáhu crew depended on departing the drop zone before being detected. The resulting weapon was the Patish (פַּטִּישׁ or 'Hammer'), a pop-up missile design whose body enclosed the same penetrator as had the free-fall Mas'mer.

Kosher Hustler - the B-58i Ariyyáhu (Part 5)

The Patish 'shape' was not entirely new (like Mas'mer, Patish was based on US data about the B-58A's BLU-2 fuel-and-weapons pod -- although, in this case, the lower component). The stand-off capability was provided by simply strapping two booster rockets from the Accular SSM. The Patish had delta lifting surfaces (initially folding for take-off but later fixed in their deployed configuration). As on the BLU-2, a fixed upper fin also acted as a rear mounting point. A new lower fin (which folded to port for take-off) acted as the rudder. Stabilizers were in the form of canard delta surfaces.

On launch, the Accular boosters were lit and the Patish 'shape' was releasesd to fly a pre-programmed flight path. At the top of its parabolic arc, the spent booster rockets were ejected (and deployed passive RF enhancement 'targets', allowing the falling booster tubes to act as both radar and IR decoys). The stabilizers then tipped the missile body into its dive. At this stage, GPS terminal guidance began with fine tuning by the delta stabilizers.

The system was simple [1] but not fool-proof. This was discovered during the first 'live' test of the Patish system. Upon lighting the Accular booster rockets, the weapons officer discovered that the pylon release mechanisms would not function. Only through violent manoeuvring could the Ariyyáhu be freed of it payload. Unfortunately, as the unarmed Patish 'shape' parted company with the bomber, the B-58i pitched up and entered a spin. Flying at only 1,500 metres, there was no chance of recovering from this spin and the test crew promptly ejected. Ariyyáhu 61-2067 crashed into the Mediterranean off Ashqelon.

[Below] Ariyyáhu 61-2067 as she appeared at the time of her loss. Not that most identifying markings have been at least partially removed by this stage. The Patish test payload carried no fuel and the penetrator 'tube' was filled with sand for ballast.

No idea to be honest.  I have never seen anything close to it in a drawing or image so it may have been Monogram's interpretation of the bomb/fuel pod with some embellishments.  Others may have more information on it and hopefully they will share what they know or show us where to find it.

Kosher Hustler - the B-58i Ariyyáhu (Part 6)

The IDF faced two challenges in operating the B-58i Ariyyáhu fleet. The first was ensuring access to high-resolution US satellite imagery (for planning navigation and targetting). The second was the modest amount of airframe time remaining on decades-old aircraft never intended for the rigors of low-altitude operations.

The first problem required careful manoeuvring around US intelligence agencies. The second problem was more easily skirted. Rather than using up Ariyyáhu airframe life, most aerial training was performed in surrogate aircraft. Crew training was performed in mission-modified IAI 1124TB Westwinds (complete with Ariyyáhu radar and navigation pods). Dedicated pilot and weapons officer training was done in dedicated Kfir trainers known as the 'Gur-aryeh' ("Lion cub").

Despite these precautions, the IDF's remaining Ariyyáhus had to be grounded in 2009. Outside of museums, the B-58 Hustler was to be seen no more.
