Short footage of a BAE Archer SPG launching a Bonus Mk2 anti armour submunition. Against massed armoured and other vehicles, these can be devastatingly effective.

Interesting video of an Elbit Sting 12km range tri-mode 120mm guided mortar bomb launching from a Cardom 120mm mortar. If we are going 120mm mortar, we should consider something like this.

Initial Operating Capability 1 was achieved in 2014, 4 years later than planned, and 7 years later than envisaged at contract award. FOC was also slipped to 2017. IOC 2 was achieved in 2016. Full Operating Capability (FOC) was achieved in 2018, a decade after Phoenix OSD

By the end of 2013, the leased Hermes 450’s had flown over 70,000 hours across 5 task lines. In March 2014, the MoD announced that Watchkeeper had been given clearance to begin flying training in the UK with Royal Artillery aircrew.

Flight testing continued, in 2011, Watchkeeper flew a 14-hour flight in which it was flown to its service ceiling of 4,880m (ca. 16,010 ft) and 115 km from the West Wales Airport. In 2011, it was announced that Watchkeeper would be deployed to Afghanistan the following year.

In 2007, the UK acquired Predator B/Reaper under an urgent operational requirement. As a stop-gap for use in Iraq and Afghanistan, the MoD obtained a number of Hermes 450’s from Thales UK in 2007 under Project Lydian, operated by a military/civilian mix of personnel.

It was also announced that the smaller vehicle would now no longer be part of the programme. Watchkeeper would be a single air vehicle with a two-sensor payload and a ground control station mounted on a Supacat vehicle that could be carried onboard a C-130 Hercules.

Thales and Northrop Grumman were down selected for the Assessment Phase. £8m contracts were awarded to the two down selected bidders for risk reduction work. In July 2004, Thales was selected as preferred bidder and the contract award was in 2005 with a planned in-service date of 2007.

Watchkeeper was still joint, the RAF were interested in its bomb damage assessment and target designation capabilities. The RN included a range of maritime and littoral battlespace capability requirements, in addition to support for the RM

The SENDER ITT was issued to Aérospatiale Matra, Bell Textron, GKN Westland, Hunting, Thomson-CSF, Lockheed Martin, Matra BAe Dynamics, Northrop Grumman, Racal, Raytheon and TRW. Planned In Service Date (ISD) was 2008, coinciding with Phoenix Out of Service Date (OSD)

SENDER was also intended to have minefield detection and electronic warfare payloads. SPECTATOR was a larger system designed for higher levels (Brigade/Division) than SENDER, with a 150 km range and dual electro-optical and synthetic aperture radar payloads.

Battlegroup Unmanned Aircraft (BgUMA) evolved into two discrete requirements, SENDER and SPECTATOR. SENDER was also integral to ASTOR and TRACER, fully joined up thinking from the MoD. It was a battalion relevant system with a 30 km range and an electro-optical and IR payload

DERA (with Cranfield Aerospace and Tasuma) had demonstrated the Observer system to serve as a test bed for future systems, first flight in 1999. The MoD was supporting UAV research a decade before Phoenix left service under the Battlegroup Unmanned Aircraft (BgUMA) programme

In the previous thread, Phoenix was withdrawn from service in 2008, but the story of Watchkeeper starts ten years before, in the 1998 Strategic Defence Review.

The lesson is simple, it matters not one jot who was right or wrong, whether it was a sneaky underhand tactic or merely a mistake, everyone lost, everyone lost because military aspiration and financial reality were strangers Wonder where we have heard that before END

As Dr Bradbury argues, inter service rivalry and politicking merely delayed the inevitable decisions that came, those decisions were about resource constraint rather than anything else.

Both the Foreign Office AND Treasury were opposed, and the RAF/RN politics and in-fighting (of which there were in abundance) and shoddy staff work merely added to the atmosphere.

In reality, this was a minor sideshow of little or no relevance to the Royal Navy CVA01 or Royal Air Force F-111, both were cancelled.

As told, what happened is the RAF used a map with an incorrect projection in a presentation that gave the impression that Australia was closer to Singapore than it was, favouring their F-111 and land basing strategy (soon after TSR2 cancellation) instead of CVA01

The truth is boring, ambiguous, and had precisely zero impact on the cancellation of the aircraft carrier in question. Various sources are attributed to the accusation, Admiral Raymond Lygo and Sir Michael Quinlan being often described as the source of the Nile!

This is one of those recurring themes that people love to discuss, whether they think it is a yes or a no, and they remain convinced that there are either mountains of evidence, or none. People also assume that no one has ever actually looked
